FIELD OF THE INVENTION
The example embodiments disclosed herein relate to systems
and/or methods for establishing authenticity of electronic records in an archives
system including any system for retaining digital information. More particularly,
certain example embodiments disclosed herein relate to techniques that are scalable
essentially without limitation for establishing and maintaining comprehensive authenticity
of electronic records over an indefinite period of time in a substantially obsolescence-proof
BACKGROUND AND SUMMARY OF THE INVENTION
Since the earliest history, various institutions (e.g.,
governments and private companies alike) have recorded their actions and transactions.
Subsequent generations have used these archival records to understand the history
of the institution, the national heritage, and the human journey. These records
may be essential to support the efficiency of the institution, to protect the rights
of individuals and businesses, and/or to ensure that the private company or public
corporation/company is accountable to its employees/shareholders and/or that the
Government is accountable to its citizens.
With the advance of technology into a dynamic and unpredictable
digital era, evidence of the acts and facts of institutions and the government and
our national heritage are at risk of being irrecoverably lost. The challenge is
pressing - as time moves forward and technologies become obsolete, the risks of
loss increase. It will be appreciated that a need has developed in the art to develop
an electronic records archives system and method especially, but not only, for the
National Archives and Records Administration (NARA) in a system known as Electronic
Records Archives (ERA), to resolve this growing problem, in a way that is substantially
obsolescence-proof and policy neutral. While embodiments of the invention will be
described with respect to its application for safeguarding government records, the
described embodiments are not limited to archives systems applications nor to governmental
applications and can also be applied to other large scale storage applications,
in addition to archives systems, and for businesses, charitable (e.g., non-profit)
and other institutions, and entities.
One aspect of the invention is directed to an architecture
that will support operational, functional, physical, and interface changes as they
occur. In one example, a suite of commercial off-the-shelf (COTS) hardware and software
products has been selected to implement and deploy an embodiment of the invention
in the ERA, but the inventive architecture is not limited to these products. The
architecture facilitates seamless COTS product replacement without negatively impacting
the ERA system.
1.1 Understanding the Problem
Another aspect of the ERA is to preserve and to provide
ready access to authentic electronic records of enduring value.
In one embodiment, the ERA supports and flows from NARA's
mission to ensure "for the Citizen and the Public Servant, for the President and
the Congress and the Courts, ready access to essential evidence." This mission facilitates
the exchange of vital ideas and information that sustains the United States of America.
NARA is responsible to the American people as the custodian of a diverse and expanding
array of evidence of America's culture and heritage, of the actions taken by public
servants on behalf of American citizens, and of the rights of American citizens.
The core of NARA's mission is that this essential evidence must be identified, preserved,
and made available for as long as authentic records are needed - regardless of form.
The creation and use of an unprecedented and increasing
volume of Federal electronic records - in a wide variety of formats, using evolving
technologies - poses a problem that the ERA must solve. An aspect of the invention
involves an integrated ERA solution supporting NARA's evolving business processes
to identify, preserve, and make available authentic, electronic records of enduring
value - for as long as they are needed.
In another embodiment, the ERA can be used to store, process,
and/or disseminate a private institution's records. That is, in an embodiment, the
ERA may store records pertaining to a private institution or association, and/or
the ERA may be used by a first entity to store the records of a second entity. System
solutions, no matter how elegant, may be integrated with the institutional culture
and organizational processes of the users.
1.1.1 NARA's Evolving Business Processes
Since 1934, NARA has developed effective and innovative
processes to manage the records created or received, maintained or used, and destroyed
or preserved in the course of public business transacted throughout the Federal
Government. NARA played a role in developing this records lifecycle concept and
related business processes to ensure long-term preservation of, and access to, authentic
archival records. NARA also has been instrumental in developing the archival concept
of an authentic record that consists of four fundamental attributes: content, structure,
context, and presentation.
NARA has been managing electronic records of archival value
since 1968, longer than almost anyone in the world. Despite this long history, the
diverse formats and expanding volume of current electronic records pose new challenges
and opportunities for NARA as it seeks to identify records of enduring value, preserve
these records as vital evidence of our nation's past, and make these records accessible
to citizens and public servants in accordance with statutory requirements.
The ERA should support, and may affect, the institution's
(e.g., NARA's) evolving business processes. These business processes mirror the
records lifecycle and are embodied in the agency's statutory authority:
- Providing guidance to Federal Agencies regarding records creation and records
- Scheduling records for appropriate disposition;
- Storing and preserving records of enduring value; and/or
- Making records available in accordance with statutory and regulatory provisions.
Within this lifecycle framework, the ERA solution provides
an integrated and automated capability to manage electronic records from: the identification
and capture of records of enduring value; through the storage, preservation, and
description of the records; to access control and retrieval functions.
Developing the ERA involves far more than just warehousing
data. For example, the archival mission is to identify, preserve, and make available
records of enduring value, regardless of form. This three-part archival mission
is the core of the Open Archival Information System (OAIS) Reference Model, expressed
as ingest, archival storage, and access. Thus, one ERA solution is built around
the generic OAIS Reference Model (presented in Figure 1), which supports these core
archival functions through data management, administration, and preservation planning.
The ERA may coordinate with the front-end activities of
the creation, use, and maintenance of electronic records by Federal officials. This
may be accomplished through the implementation of disposition agreements for electronic
records and the development of templates or schemas that define the content, context,
structure, and presentation of electronic records along with lifecycle data referring
to these records.
The ERA solution may complement NARA's other activities
and priorities, e.g., by improving the interaction between NARA staff and their
customers (in the areas of scheduling, transfer, accessioning, verification, preservation,
review and redaction, and/or ultimately the ease of finding and retrieving electronic
1.1.2 Encompassing a Broad Scope of Records
Like NARA itself, the scope of ERA includes the management
of electronic and non-electronic records, permanent and temporary records, and records
transferred from Federal entities as well as those donated by individuals or organizations
outside of the government. Each type of record is described and/or defined below.
ERA and Non-Electronic Records: Although the focus of ERA is on preserving
and providing access to authentic electronic records of enduring value, the system's
scope also includes, for example, management of specific lifecycle activities for
non-electronic records. ERA will support a set of lifecycle management processes
(such as those used for NARA) for appraisal, scheduling, disposition, transfer,
accessioning, and description of both electronic and non-electronic records. A common
systems approach to appraisal and scheduling through ERA will improve the efficiency
of such tasks for non-electronic records and help ensure that permanent electronic
records are identified as early as possible within the records lifecycle. This same
common approach will automate aspects of the disposition, transfer, accessioning,
and description processes for all types of records that will result in significant
workflow efficiencies. Archivists, researchers, and other users may realize benefits
by having descriptions of both electronic and non-electronic records available together
in a powerful, universal catalog of holdings. In an embodiment, some of ERA's capabilities
regarding non-electronic records may come from subsuming the functionality of legacy
systems such the Archival Research Catalog (ARC). To effectively manage lifecycle
data for all types of records, in certain embodiments, ERA also may maintain data
interchange (but not subsume) other legacy systems and likely future systems related
to non-electronic records.
Permanent and Temporary Records: There is a fundamental archival distinction
between records of enduring historic value, such as those that NARA must retain
forever (e.g., permanent records) and those records that a government must retain
for a finite period of time to conduct ongoing business, meet statutory and regulatory
requirements, or protect rights and interests (e.g., temporary records).
For a particular record series from the US Federal Government,
NARA identifies these distinctions during the record appraisal and scheduling processes
and they are reflected in NARA-approved disposition agreements and instructions.
Specific records are actually categorized as permanent or temporary during the disposition
and accessioning processes. NARA takes physical custody of all permanent records
and some temporary records, in accordance with approved disposition agreements and
instructions. While all temporary records are eventually destroyed, NARA ultimately
acquires legal (in addition to physical) custody over all permanent records.
ERA may address the distinction between permanent and temporary
records at various stages of the records life-cycle. ERA may facilitate an organization's
records appraisal and scheduling processes where archivists and transferring entities
may use the system to clearly identify records as either permanent or temporary
in connection with the development and approval of disposition agreements and instructions.
The ERA may use this disposition information in association with the templates to
recognize the distinctions between permanent and temporary records upon ingest and
manage these records within the system accordingly.
For permanent records this may involve transformation to
persistent formats or use of enhanced preservation techniques to insure their preservation
and accessibility forever. This also may apply to temporary records of long-term
value, such as, for example, medical records. For example, any record that must
be retained beyond the life of its originating system may need one or more "transformations"
that maintain the authenticity of the records. For temporary records, NARA's Records
Center Program (RCP) is exploring offering its customers an ERA service to ingest
and store long-term temporary records in persistent formats. To the degree that
the RCP opts to facilitate their customers' access to the ERA for appropriate preservation
of long-term temporary electronic records, this same coordination relationship with
transferring entities through the RCP will allow NARA to effectively capture permanent
electronic records earlier in the records lifecycle. In the end, ERA may also provide
for the ultimate destruction of temporary electronic records.
ERA and Donated Materials: In addition to federal records, NARA also receives
and accesses donated archival materials. Such donated collections comprise a significant
percentage of NARA's Presidential Library holdings, for example. ERA may manage
donated electronic records in accordance with deeds of gift of deposit agreements
which, when associated with templates, may ensure that these records are properly
preserved and made available to users. Although donated materials may involve unusual
disposition instructions or access restrictions, ERA should be flexible enough to
adapt to these requirements. Since individuals or institutions donating materials
to NARA are likely to be less familiar with ERA than federal transferring entities,
the system may also include guidance and tools to help donors and the NARA appraisal
staff working with them insure proper ingest, preservation, dissemination of donated
1.1.3 Meeting the Needs of Users
Systems are designed to facilitate the work of users, and
not the other way around. One or more of the following illustrative classes of users
may interact with the ERA: transferring entity; appraiser; records processor; preserver;
access reviewer; consumer; administrative user; and/or a manager. The ERA may take
into account data security, business process re-engineering, and/or systems development
and integration. The ERA solution also may provide easy access to the tools the
users need to process and use electronic records holdings efficiently.
1.2 Mitigating Risks and Meeting Challenges
NARA must meet challenges relating to archiving massive
amounts of information, or the American people risk losing essential evidence that
is only available in the form of electronic federal records. But beyond mitigating
substantial risks, the ERA affords such opportunities as:
- Using digital communication tools, such as the Internet, to make electronic
records holdings, such as NARA's, available beyond the research room walls in offices,
schools, and homes throughout the country and around the world;
- Allowing users to take advantage of the information-processing efficiencies
and capabilities afforded by electronic records;
- Increasing the return on the public's investment by demonstrating technological
solutions to electronic records problems that will be applied throughout our digital
society in a wide variety of institutional settings; and/or
- Developing tools for archivists to perform their functions more efficiently.
According to one aspect of the invention, there is provided
a system for ingesting, storing, and/or disseminating information. The system may
include an ingest module, a storage module, and a dissemination module that may
be accessed by a user via one or more portals.
In an aspect of certain embodiments, there is provided
a system and method for automatically identifying, preserving, and disseminating
archived materials. The system/method may include extreme scale archives storage
architecture with redundancy or at least survivability, suitable for the evolution
from terabytes to exabytes, etc.
In another aspect of certain embodiments, there is provided
an electronic records archives (ERA), comprising an ingest module to accept a file
and/or a record, a storage module to associate the file or record with information
and/or instructions for disposition, and an access or dissemination module to allow
selected access to the file or record. The ingest module may include structure and/or
a program to create a template to capture content, context, structure, and/or presentation
of the record or file. The storage module may include structure or a program to
preserve authenticity of the file or record over time, and/or to preserve the physical
access to the record or file over time. The access module may include structure
and/or a program to provide a user with the ability to view/render the record or
file over time, to control access to restricted records, to redact restricted or
classified records, and/or to provide access to an increasing number of users anywhere
at any time.
The ingest module may include structure or a program to
auto-generate a description of the file or record. Each record may be transformed,
e.g., using a framework that wraps and computerizes the record in a self-describing
format with appropriate metadata to represent information in the template.
The ingest module, may include structure or a program to
process a Submission Information Package (SIP), and/or an Archival Information Package
(AIP). The access module may include structure or a program to process a Dissemination
Information Packages (DIP).
Independent aspects of the invention may include the ingest
module alone or one or more aspects thereof, the storage module alone or one or
more aspects thereof; and/or the access module alone or one or more aspects thereof.
Still further aspects of the invention relate to methods
for carrying out one or more functions of the ERA or components thereof (ingest
module, storage module, and/or access module).
1.3 Archival Problems in General and Drawbacks of Existing Solutions
It is not enough just to preserve electronic records.
Now and into the future, archivists must be able to attest to the authenticity
of the preserved records to protect the rights and interests of various constituents.
If records cannot be certified as authentic, there is a risk of unraveling the trust
system upon which society is based
In the words of Jeff Rothenberg of the Rand Corporation:
- The relationship between digital preservation and authenticity stems from the
fact that meaningful preservation implies the usability of that which is preserved.
That is, the goal of preservation is to allow future users to retrieve, access,
decipher, view, interpret, understand, and experience documents, data, and records
in meaningful and valid (that is authentic) ways. An informational entity that is
"preserved" without being usable in a meaningful and valid way has not been meaningfully
preserved, i.e., has not been preserved at all.
- The difficulty of defining a viable digital preservation strategy is partly
the result of our failing to understand and appreciate the authenticity issues surrounding
digital informational entities and the implications of these issues for potential
technical solutions to the digital preservation problem. (See
Jeff Rothenberg, Preserving Authentic Digital Information," in Authenticity
in a Digital Environment, May 2000. Council on Library and Information Resources,
. Available at: www.clir.org/pubs/abstract/pub92abst.html.)
In order to establish a common understanding, it is important
to clarify four key concepts and the relationships among them - namely, reliability,
authenticity, authentication, and trustworthiness.
The InterPARES Project, an international collaboration
researching the preservation of electronic records, defined reliability and authenticity.
These definitions, in turn, have been adopted by most subsequent research projects
and initiatives. A reliable record stands for the facts it contains - the record's
content can be trusted. The reliability of a record depends upon, for example the
completeness of the record's form, the control exercised over the process of creation,
A reliable record has authority - that is, there is knowledge
of who created the record, when it was created, how it was created, and the purpose
for which it was created. Reliability generally is more the concern of the record's
creator than its preserver. In some ways, reliability is a "given" (e.g., must be
assumed) before records ever reach the electronic archives. Although unreliable
records generally cannot be made reliable, the issue of reliability cannot be ignored.
In this vein, there are two options for establishing a
policy related to the reliability of submitted records. First, all records submitted
by institutions may be accepted. In this case it will be assumed that the records
are reliable because the providers say so. Second, reliability criteria that providers
must meet before records will be accepted may be established. The criteria may deal
with completeness of the record, procedural controls over the creation of the records,
etc. For example, the Authenticity Task Force of the InterPARES Project has established
a set of criteria that may be used as a basis for setting such criteria.
The InterPARES Project defines an authentic record as "a
record that is what it purports to be and is free from tampering or corruption."
Broadly considered, the authenticity of records depends upon actions by both the
Records Creator and the Records Preserver. In particular, the Records Creator generally
is concerned with the "truth" of the original record, including, for example, the
mode, form, and/or state of transmission of the records as drafts, originals, and/or
copies. The Records Preserver generally is concerned with the manner of the maintenance,
preservation, and custody of the records. The mode of transmission of the record
generally is the means used to transmit a record across space and time, whereas
the form of transmission generally is the physical carrier on which a record is
received (e.g., paper, film, disk, magnetic tape, etc.).
For a record to be authentic (meaning that the record remains
reliable over time), its preservation should occur under strict controls. Some questions
that may be used when determining whether a record is authentic follow:
- When was a record copied or migrated?
- Who did the copying or migration?
- How did the copying or migration take place?
- What quality control processes governed the copying or migration?
"Trust" and "truthfulness" have become key aspects of an
authentic record. Because conformity with "the truth" is a judgment, a determination
of authenticity likewise will be a judgment. For example, though it is necessary
to have an accurate bit stream, such a bit stream is not sufficient to have an "authentic
record." It is this broad sense of authenticity that must be addressed. Indeed,
authenticity includes issues such as, for example, integrity, completeness, correctness,
validity, faithfulness to an original, meaningfulness, and suitability for an intended
Although "authenticity" and "authentication" often are
used together, they sometimes may be thought of as quite different concepts. By
way of example and without limitation, authentication sometimes may be thought of
as being a narrower term than authenticity. For example, authentication generally
is a declaration about a record at a given time. The rules governing authentication
may be established by legislation or other policy. Authentication generally means
that the custodian of a record issues a statement saying that a record is authentic
at this time. Authentication thus may be thought of as being external to the record
itself and is temporary (as opposed to authenticity, which is a quality of the record
that is to be constantly protected over the long-term). An "authenticated record"
only can be as reliable as when the record was first issued by its creator. It certain
embodiments, it may be useful to authenticate (e.g., certify) a record from time-to-time
to indicate that authenticity is being maintained.
The Minnesota Historical Society has defined the concept
of a "trustworthy information system." As stated in the TIS Handbook, "Trustworthiness
refers to an information system's accountability and its ability to produce reliable
and authentic information and records." In an embodiment, documentation and metadata
are a part of a trustworthy information system, as they are useful in proper data
creation, storage, retrieval, modification, retention, destruction, and the like.
Ensuring the authenticity over time of digital records
is a major concern that has at least two aspects. A first aspect relates to checking
and certifying data integrity (e.g., associated with technical processes such as
integrity checking, certification, digital watermarking, steganography, and/or user
and authentication protocols). A second aspect relates to identifying the intellectual
qualities of information that make it authentic (e.g., associated with legal, cultural,
and/or philosophical concepts such as trustworthiness and completeness).
According to Anne Gilliland-Swetland, "Preserving knowledge
is more complex than preserving only media or content. It is about preserving the
intellectual integrity of information objects, including capturing information about
the various contexts within which information is created, organized, and used; organic
relationships with other information objects; and characteristics that provide meaning
and evidential value." Accordingly, one feature of certain example embodiments relates
to preserving knowledge and making it available. This complex task involves both
technical and intellectual challenges.
Unfortunately, commercial systems for electronic archiving
are built around storage and/or workflow technologies but do not provide the highest
levels of authenticity support over indefinite periods of time. Moreover, commercial
systems also tend to target archival needs within an enterprise and sometimes for
compliance with targeted government regulations, such as Sarbanes Oxley, whereas
a complete archives system (such as NARA) must accept records and other associated
electronic assets (e.g., administrative information about the records) from other
enterprises and has more stringent archival requirements. For example, as the custodian
of the nation's archived electronic assets, NARA has to support basic rights of
citizens and obligations of the government, such as military pensions and patents,
which lead, for example, to indefinite retention requirements. Also, current electronic
records archives systems and processes are manually intensive and do not provide
comprehensive support for electronic records authenticity.
For example, it is noted that there are current commercial
off-the-shelf (COTS) products that provide some elements of authenticity, but not
all elements. EMC's Documentum and Centera products are examples. Certain example
systems have implemented Documentum for forms (e.g., entry), workflow infrastructure,
and content management of some data (e.g., business objects). Centera is a storage
system that provides protection and some metadata and search capabilities, but it
does not provide processes for authenticity. In general, COTS products would address
specific regulatory requirements, such as, for example, Sarbanes Oxley, if anything,
which target commercial business, rather than more stringent needs (e.g., of NARA)
that the drive innovative solution of the example embodiments.
Thus, it will be appreciated that there is a need in the
art for improved systems and/or methods that is/are scalable essentially without
limitation for establishing and maintaining comprehensive authenticity of electronic
records over an indefinite period of time in a substantially obsolescence-proof
According to certain example embodiments, a system for
establishing and maintaining authenticity of a plurality of records and/or documentary
materials to be persisted in an electronic archives system is provided. Safeguarding
programmed logic circuitry may be configured to safeguard each said record and/or
documentary material throughout its entire lifecycle by monitoring and recording
both intended changes to each said record and/or documentary material and its corresponding
status, as well as unintended changes to each said record and/or documentary material.
Extracting and preserving programmed logic circuitry may be configured to extract
and preserve context and structure associated with each said record and/or documentary
material. Custody programmed logic circuitry may be configured to establish and
preserve substantially uninterrupted proof-of-custody including at least a source
for each said record and/or documentary material throughout its entire lifecycle.
Essential characteristic programmed logic circuitry may be configured to capture
and preserve essential characteristics of each said record and/or documentary material
throughout its lifecycle in dependence on one or more changeable definitions of
essential characteristic. At least one storage location may be configured to store
the plurality of records and/or documentary materials and all preserved information.
The archives system may be scalable essentially without limitation. The authenticity
of the plurality of records and/or documentary materials may be comprehensively
storable and maintainable over an indefinite period of time in a substantially obsolescence-proof
manner despite changeability of the records and/or documentary materials, record
and/or documentary material custody, and/or essential characteristic definitions.
According to certain other example embodiments, a computer-implemented
method tangibly embodied by at least instructions stored on a computer-readable
storage medium for establishing and maintaining authenticity of a plurality of records
and/or documentary materials to be persisted in an electronic archives system is
provided. Each record and/or documentary material may be safeguarded throughout
its entire lifecycle by monitoring and recording both intended changes to each said
record and/or documentary material and its corresponding status, as well as unintended
changes to each said record and/or documentary material. Context and structure associated
with each said record and/or documentary material may be extracted and preserved.
Substantially uninterrupted proof-of-custody including at least a source may be
established and preserved for each said record and/or documentary material throughout
its entire lifecycle. Essential characteristics of each said record and/or documentary
material may be captured and preserved throughout its lifecycle in dependence on
one or more changeable definitions of essential characteristic. The plurality of
record and/or documentary material and all preserved information may be stored.
The archives system may be scalable essentially without limitation. The authenticity
of the plurality of record and/or documentary material may be comprehensively storable
and maintainable over an indefinite period of time in a substantially obsolescence-proof
manner despite changeability of the records and/or documentary materials, record
and/or documentary material custody, and/or essential characteristic definitions.
According to still other example embodiments, a computer-implemented
method tangibly embodied by at least instructions stored on a computer-readable
storage medium for establishing and maintaining authenticity of a plurality of records
and/or documentary materials to be persisted in an electronic archives system is
provided. Transfer media from a transferring entity may be inspected to ensure that
said transfer media contains at least one record and/or documentary material to
be ingested. The at least one record and/or documentary material to be ingested
may be stored in a temporary storage location. That the transfer media is mounted
for upload into the system may be ensured. At least one security and/or integrity
check may be performed on the transfer media. At least one validation check may
be performed on the at least one record's and/or documentary material's bit-stream.
The at least one record and/or documentary material may be stored to at least one
managed storage location. Any outstanding verification issues with the transferring
entity may be resolved. Necessary metadata for the at least one record's and/or
documentary material's lifecycle may be persisted. The archives system may be scalable
essentially without limitation. The authenticity of the plurality of records and/or
documentary materials may be comprehensively storable and maintainable over an indefinite
period of time in a substantially obsolescence-proof manner despite changeability
of the records and/or documentary materials, record and/or documentary material
custody, and/or essential characteristic definitions.
It will be appreciated that these techniques may be applied
to records, assets, and/or documentary materials. It also will be appreciated that
documentary materials may encompass a variety of different items. For example, in
certain embodiments, documentary materials may be considered a collective term for
records, nonrecord materials, and/or personal papers, that refers to all media on
which information is recorded, regardless of the nature of the medium or the method
or circumstances of recording. In certain other embodiments, documentary materials
may include, for example, records (e.g., temporary and/or permanent), non-record
material, personal papers or artifacts that refer to all media containing recorded
information, regardless of the nature of the media or the method(s) or circumstance(s)
of recording. In still other embodiments, documentary materials may be comprised
of electronic information on physical media or paper records that are shipped to
the archives in containers (e.g. box, envelope, etc), and those documentary materials
that include electronic information may be transmitted via HTTPS or SFTP and divided
into virtual electronic containers by the system. This need not be a user activity,
but instead may be performed by the packaging tool as an aid to optimize transmission
via electronic means.
It will be appreciated that as used herein, the term "subroutine"
is broad enough to encompass any suitable combination of hardware, software, and
any other form of programmed logic circuitry (which itself may be any suitable combination
of hardware, software, firmware, or the like) capable of accomplishing a specified
function. It also will be appreciated that the above-described embodiments, and
the elements thereof, may be used alone or in various combinations to realize yet
Other aspects, features, and advantages of this invention

The following description includes several examples and/or
embodiments of computer-driven systems and/or methods for carrying out automated
information storage, processing and/or access. In particular, one or more examples
and embodiments are focused on systems and/or methods oriented specifically for
use with the U.S. National Archives and Records Administration (NARA). However,
it will be recognized that, while one or more portions of the present specification
may be limited in application to NARA's specific requirements, most if not all of
the described systems and/or methods have broader application. For example, the
implementations described for storage, processing, and/or access to information
(also sometimes referred to as ingest, storage, and dissemination) can also apply
to any institution that requires and/or desires automated archiving and/or preservation
of its information, e.g., documents, email, corporate IP/knowledge, etc. The term
"institution" includes at least government agencies or entities, private companies,
publicly traded corporations, universities and colleges, charitable or non-profit
organizations, etc. Moreover, the term "electronic records archive" (ERA) is intended
to encompass a storage, processing, and/or access archives for any institution,
regardless of nature or size.
As one example, NARA's continuing fulfillment of its mission
in the area of electronic records presents new challenges and opportunities, and
the embodiments described herein that relate to the ERA and/or authenticity techniques
may help NARA fulfill its broadly defined mission. The underlying risk associated
with failing to meet these challenges or realizing these opportunities is the loss
of evidence that is essential to sustaining a government's or an institution's needs.
Figure 2 relates specific electronic records challenges to the components of the
OAIS Reference Model (ingest, archival storage, access, and data management/administration),
and summarizes selected relevant research areas.
At Ingest - the ERA needs to identify and capture all components of the record
that are necessary for effective storage and dissemination (e.g., content, context,
structure, and presentation). This can be especially challenging for records with
dynamic content (e.g., websites or databases).
Archival Storage - Recognizing that in the electronic realm the logical record
is independent of its media, the four illustrative attributes of the record (e.g.,
content, context, structure, and presentation) and their associated metadata, still
must be preserved "for the life of the Republic."
Access - NARA will not fulfill its mission simply by storing electronic records
of archival value. Through the ERA, these records will be used by researchers long
after the associated application software, operating system, and hardware all have
become obsolete. The ERA also may apply and enforce access restrictions to sensitive
information while at the same time ensuring that the public interest is served by
consistently removing access restrictions that are no longer required by statute
Data Management - The amount of data that needs to be managed in the ERA
can be monumental, especially in the context of government agencies like NARA. Presented
herewith are embodiments that are truly scalable solutions that can address a range
of needs - from a small focused Instance through large Instances. In such embodiments,
the system can be scaled easily so that capacity in both storage and processing
power is added when required, and not so soon that large excess capacities exist.
This will allow the system to be scaled to meet demand and provide for maximum flexibility
in cost and performance to the institution (e.g., NARA).
Satisfactorily maintaining authenticity through technology-based
transformation and re-representation of records is extremely challenging over time.
While there has been significant research about migration of electronic records
and the use of persistent formats, there has been no previous attempt to create
an ERA solution on the scale required by some institutions such as NARA.
Migrations are potentially loss-full transformations, so
techniques are needed to detect and measure any actual loss. The system may reduce
the likelihood of such loss by applying statistical sampling, based on human judgment
for example, backed up with appropriate software tools, and/or institutionalized
in a semi-automatic monitoring process.
Table 1 summarizes the "lessons learned" by the Applicants
from experience with migrating different types of records to a Persistent Object
Type of record
Current Migration Possibilities
The Dutch Testbed project has shown that e-mail can be successfully migrated
to a POF. An XML-based POF was designed by Tessella as part of this work. Because
e-mail messages can contain attached files in any format, an e-mail record should
be preserved as a series of linked objects: the core message, including header information
and message text, and related objects representing attachments. These record relationships
are stored in the Record Catalog. Thus, an appropriate preservation strategy can
be chosen and applied to each file, according to its type.
Word processing documents
Simple documents can be migrated to a POF, although document appearance can
be complex and may include record characteristics. Some documents can also include
other embedded documents which, like e-mail attachments, can be in any format. Documents
can also contain macros that affect "behavior" and are very difficult to deal with
generically. Thus, complex documents currently require an enhanced preservation
Adobe's Portable Document Format (PDF) often has been treated as a suitable
POF for Word documents, as it preserves presentation information and content. The
PDF specification is controlled by Adobe, but it is published, and PDF readers are
widely available, both from Adobe and from third-parties. ISO, with assistance from
NARA, has developed a standard version of PDF specifically designed for archival
purposes (PDF/A, see ISO 19005-1). This format has the benefit that it forces some
ambiguities in the original to be removed. However, both Adobe and Microsoft are
evolving towards using native XML for their document formats.
TIFF is a widely accepted open standard format for raster images and is a
good candidate in the short to medium term for a POF. For vector images, the XML-based
Scalable Vector Graphics format is an attractive option, particularly as it is a
Worldwide Web Consortium (W3C) open standard.
The contents of a database should be converted to a POF rather than being
maintained in the vendor's proprietary format.
Migration of the contents of relational database tables to an XML or flat
file format is relatively straightforward. However, in some cases, it is also desirable
to represent and/or preserve the structure of the database. In the Dutch Digital
Preservation Testbed project, this was achieved using a separate XML document to
define the data types of columns, constraints (e.g., whether the data values in
a column must be unique), and foreign key relationships, which define the inter-relationships
between tables. The Swiss Federal Archives took a similar approach with their SIARD
tool, but used SQL statements to define the database structure.
Major database software vendors have taken different approaches to implementing
the SQL "standard" and add extra non-standard features of their own. This complicates
the conversion to a POF.
Another difficulty is the Binary Large Object (BLOB) datatype, which presents
similar problems to those of e-mail attachments: any type of data can be stored
in a BLOB and in many document-oriented databases, the majority of the important
or relevant data may be in this form. In this case, separate preservation strategies
may be applied according to the type of data held.
A further challenge with database preservation is that of preserving not
only the data, but the way that the users created and viewed the data. In some cases
this may be depend on stored queries and stored procedures forming the database;
in others it may depend on external applications interacting with the database.
To preserve such "executable" aspects of the database "as a system" is an area of
Records with a high degree of "behavioral" properties (e.g., virtual reality
For this type of record, it is difficult to separate the content from the
application in which it was designed to operate. This makes these records time-consuming
to migrate to any format. Emulation is one approach, but this approach is yet to
be fully tested in an archival environment. Migration to a POF is another approach,
and more research is required into developing templates to support this.
The Dutch Testbed project examined the preservation of spreadsheets and concluded
that an XML-based POF was the best solution, though it did not design the POF in
detail. The structured nature of spreadsheet data means that it can be mapped reliably
and effectively to an XML format. This approach can account for cell contents, the
majority of appearance-related issues (cell formatting, etc), and formulae used
to calculate the contents of some cells.
The Testbed project did not address how to deal with macros: most spreadsheet
software products include a scripting or programming language to allow very complex
macros to be developed (e.g., Visual Basic for Applications as part of Microsoft
Excel). This allows a spreadsheet file to contain a complex software application
in addition to the data it holds. This is an area where further research is necessary,
though it probably applies to only a small proportion of archival material.
Most Web sites include documents in standardized formats (e.g., HTML). However,
it should be noted that there are a number of types of HTML documents, and many
Web pages will include incorrectly formed HTML that nonetheless will be correctly
displayed by current browsers. The structural relationship between the different
files in a web-site should be maintained. The fact that most web-sites include external
as well as internal links should be managed in designing a POF for web-sites. The
boundary of the domain to be archived should be defined and an approach decided
on for how to deal with links to files outside of that domain.
Many modem web sites are actually applications where the navigation and formatting
are generated dynamically from executed pages (e.g., Active Server Pages or Java
The actual content, including the user's preferences on what content is to
be presented, is managed in a database. In this case, there are no simple web pages
to archive, as different users may be presented with different material at different
times. This situation overlaps with our discussion above of databases and the applications
which interact with them.
Sound and video
For audio streams, the WAV and AVI formats are the de facto standards and
therefore a likely basis for POFs. For video, there are a number of MPEG formats
in general use, with varying degrees of compression. While it is desirable that
only lossless compression techniques are used for archiving, if a lossy compression
was used in the original format it cannot be recaptured in a POF.
For video archives in particular, there is the potential for extremely large
quantities of material. High quality uncompressed video streams can consume up to
100GB per hour of video, so storage space is an issue for this record type.
It is currently not possible to migrate a number of file
formats in a way that will be acceptable for archival purposes. One aspect is to
encourage the evolution and enhancement of third-party migration software products
by providing a framework into which such commercial off-the-shelf (COTS) software
products could become part of the ERA if they meet appropriate tests.
When an appropriate POF cannot be identified to reduce
the chances of obsolescence, the format may need to be migrated to a non-permanent
but more modem, proprietary format (this is known as Enhanced Preservation). Even
POFs are not static, since they still need executable software to interpret them,
and future POFs may need to be created that have less feature loss than an older
format. Thus, the ERA may allow migrated files to be migrated again into a new and
more robust format in the future. Through the Dutch Testbed Project, the Applicants
have found that it is normally better to return to the original file(s) whenever
such a re-migration occurs. Thus, when updating a record, certain example embodiments
may revert to an original version of the document and migrate it to a POF accordingly,
whereas certain other example embodiments may not be able to migrate the original
document (e.g., because it is unavailable, in an unsupported format, etc.) and thus
may be able to instead or in addition migrate the already-migrated file. Thus, in
certain example embodiments, a new version of a record may be derived from an original
version of the record if it is available or, if it the original is not available,
the new version may be derived from any other already existing derivative version
(e.g., of the original). As such, an extensible POF for certain example embodiments
may be provided.
In view of the above aspects of the OAIS Reference Model,
the ERA may comprise an ingest module to accept a file and/or a record, a storage
module to associate the file or record with information and/or instructions for
disposition, and an access or dissemination module to allow selected access to the
file or record. The ingest module may include structure and/or a program to create
a template to capture content, context, structure, and/or presentation of the record.
The storage module may include structure and/or a program to preserve authenticity
of the record over time, and/or to preserve the physical access to the record or
file over time. The access module may include structure or a program to provide
a user with ability to view/render the record or file over time, to control access
to restricted records, to redact restricted or classified records, and/or to provide
access to an increasing number of users anywhere at any time.
Figure 3 illustrates the notional lifecycle of records
as they move through the ERA system, in accordance with an example embodiment. Records
flow from producers, who are persons or client systems that provide the information
to be preserved, and end up with consumers, who are persons or client systems that
interact with the ERA to find preserved information of interest and to access that
information in detail. The Producer also may be a "Transferring Entity."
During the "Identify" stage, producers and archivists develop
a Disposition Agreement to cover records. This Disposition Agreement contains disposition
instructions, and also a related Preservation and Service Plan. Producers submit
records to the ERA System in a Submission Information Package (SIP). The transfer
occurs under a pre-defined Disposition Agreement and Transfer Agreement. The ERA
System validates the transferred SIP by scanning for viruses, ensuring the security
access restrictions are appropriate, and checking the records against templates.
The ERA System informs the Producer of any potential problems, and extracts metadata
(including descriptive data, described in greater detail below), creates an Archival
Information Package (or AIP, also described in greater detail below), and places
the AIP into Archival Storage. At any time after the AIP has been placed into Archival
Storage, archivists may perform Archival Processing, which includes developing arrangement,
description, finding aids, and other metadata. These tasks will be assigned to archivists
based on relevant policies, business rules, and management discretion. Archival
processing supplements the Preservation Description Information metadata in the
At any time after the AIP has been placed into Managed
Storage (also sometimes called Archival Storage), archivists may perform Preservation
Processing, which includes transforming the records to authentically preserve them.
Policies, business rules, Preservation and Service Plans, and management discretion
will drive these tasks. Preservation processing supplements the Preservation Description
Information metadata in the archives, and produces new (transformed) record versions.
With respect to the "Make Available" phase, at any time
after the AIP has been placed into Archival Storage, archivists may perform Access
Review and Redaction, which includes performing mediated searches, verifying the
classification of records, and coordinating redaction of records where necessary.
These tasks will be driven by policies, business rules, and access requests. Access
Review and Redaction supplement the Preservation Description Information metadata
in the archives, and produces new (redacted) record versions. Also, at any time
after the AIP has been placed into Managed Storage, Consumers may search the archives
to find records of interest.
Figure 4 illustrates the ERA System Functional Architecture
from a notional perspective, delineating the system-level packages and external
system entities, in accordance with an example embodiment. The rectangular boxes
within the ERA System boundary represent the six system-level packages. The ingest
system-level package includes the means and mechanisms to receive the electronic
records from the transferring entities and prepares those electronic records for
storage within the ERA System, while the records management system-level package
includes the services necessary to manage the archival properties and attributes
of the electronic records and other assets within the ERA System as well as providing
the ability to create and manage new versions of those assets. Records Management
includes the management functionality for disposition agreements, disposition instructions,
appraisal, transfer agreements, templates, authority sources, records lifecycle
data, descriptions, and arrangements. In addition, access review, redaction, selected
archival management tasks for non-electronic records, such as the scheduling and
appraisal functions are also included within the Records Management service.
The Preservation system-level package includes the services
necessary to manage the preservation of the electronic records to ensure their continued
existence, accessibility, and authenticity over time. The Preservation system-level
service also provides the management functionality for preservation assessments,
Preservation and Service Level plans, authenticity assessment and digital adaptation
of electronic records. The Archival Storage system-level package includes the functionality
to abstract the details of mass storage from the rest of the system. This abstraction
allows this service to be appropriately scaled as well as allow new technology to
be introduced independent of the other system-level services according to business
requirements. The Dissemination system-level package includes the functionality
to manage search and access requests for assets within the ERA System. Users have
the capability to generate search criteria, execute searches, view search results,
and select assets for output or presentation. The architecture provides a framework
to enable the use of multiple search engines offering a rich choice of searching
capabilities across assets and their contents.
The Local Services and Control (LS&C) system-level package
includes the functional infrastructure for the ERA Instance including a user interface
portal, user workflow, security services, external interfaces to the archiving entity
and other entities' systems, as well as the interfaces between ERA Instances. All
external interfaces are depicted as flowing through LS&C, although the present invention
is not so limited.
The ERA System contains a centralized monitoring and management
capability called ERA Management. The ERA Management hardware and/or software may
be located at an ERA site. The Systems Operations Center (SOC) provides the system
and security administrators with access to the ERA management Virtual Local Area
Network. Each SOC manages one or more Federations of Instances based on the classification
of the information contained in the Federation.
Also shown are the three primary data stores for each Instance:
- 1. Ingest Working Storage - Contains transfers that remain until they
are verified and placed into the Electronic Archives;
- 2. Electronic Archives - Contains all assets (e.g., disposition agreements,
records, templates, descriptions, authority sources, arrangements, etc.); and
- 3. Instance Data Storage - Contains a performance cache of all business
assets, operational data and the ERA asset catalog.
This diagram provides a representative illustration of
how a federated ERA system can be put together, though it will be appreciated that
the same is given by way of example and without limitation. Also, the diagram describes
a collection of Instances at the same security classification level and compartment
that can communicate electronically via a Wide Area Network (WAN) with one another,
although the present invention is not so limited. For example, Figure 5 is a federation
of ERA instances, in accordance with an example embodiment. The federation approach
is described in greater detail below, although it is important to note here that
the ERA and/or the asset catalog may be structured to work with and/or enable a
The ERA's components may be structured to receive, manage,
and process a large number of assets and collections of assets. Because of the large
number of assets and collections of assets, it would be advantageous to provide
an approach that scales to accommodate the same. Beyond the storage of the assets
themselves, a way of understanding, accessing, and managing the assets may be provided
to add meaning and functionality to the broader ERA. To serve these and/or other
ends, an asset catalog including related, enabling features may be provided.
In particular, to address the overall problems of scaling
and longevity, the asset catalog and storage system federator may address the following
underlying problems, alone or in various combinations:
- Capturing business objects that relate to assets that are particular to the
application storing the assets (e.g., in an archiving system, such business objects
may include, for example, disposition and destruction information, receipt information,
legal transfer information, appraisals and archives description, etc.), with each
new business use of the design potentially defining unique business objects that
are needed to control its assets and execute its business processes;
- Maintaining arbitrary asset attributes to be flexible in accommodating unknown
- Employing asset and other identifiers that are immutable so that they remain
useful indefinitely and, therefore, enable them to be referenced both within the
archives and by external entities with a reduced concern for changes over time;
- Supporting search and navigation through the extreme scale and diversity of
- Handling obsolescence of assets that develops over time;
- Accommodating redacted and other derivative versions of assets appropriate for
an archives system;
- Federating (e.g., integrate independent parts to create a larger whole) multiple,
potentially heterogeneous, distributed, and independent archives systems (e.g.,
instances) to provide a larger scale archives system;
- Supporting a distributed implementation necessary for scaling, site independence,
and disaster recovery considerations where the distribution of assets and associated
catalogs may change over time but remain visible to all sites;
- Employing a search architecture and catalog format that allow exploitation of
multiple, possibly commercial search engines for differing asset data types and
across instances of archives in a federation, as future needs may dictate;
- Accommodating multiple, heterogeneous, commercial storage subsystems among and
within the instances in a federation of archives to achieve extreme scaling and
adapt to changes over time;
- Supporting a variety of data handling requirements based on, for example, security
level, handling restrictions and ownership, in a manner that performs well and remains
manageable for an extremely large number of assets and catalog entries;
- Supporting storage of any kind of electronic asset;
- Supporting transparent data location and migration and storage subsystem upgrades/changes;
- Supporting reconstruction of the catalog and archives with little or no information
other than the original catalog and archived bit streams (e.g., for the purposes
of disaster recovery).
It will be appreciated that these and/or other components
described herein may be provided in any number of different combinations of hardware
and/or software components, architectures, subsystems, or the like. Indeed, any
suitable form of programmed logic circuitry including one or both of hardware and/or
software may be used in certain example embodiments.
2. Understanding Authenticity
2.1 Authenticity in General
One way to address the preservation challenge is to break
it down into three components: lessons learned from preserving authentic analog
records, technical aspects of preserving digital objects, and intellectual aspects
of preserving authentic digital records.
2.1.1 Preserving Authentic Analog Records
It has been noted that assessments of authenticity in the
world of paper and other stable, physical media rely heavily on the existence of
enduring physical objects. This stability enables at least three strategies for
- Trace the history (e.g., the "extended existence in time") of the record or
- If the object is "one of many" (such as a member of an edition), compare it
with another copy, a reference copy; and,
- If something is transient (such as a performance of a play), make use of a stable
reference object (such as the script).
Large-scale bureaucratic organizations evolved during the
nineteenth century and continue to the present day. Because they are ongoing entities,
bureaucracies had to develop a system for determining the "truth-value" of records
that were created previously. For a bureaucracy to function, its members must be
able to rely on records of events for which they have no personal knowledge.
Heather MacNeil has outlined two ways bureaucracies and
bureaucrats determine the truth-value of records:
- 1. Assess the reliability of records indirectly by focusing on the reliability
of record-makers and record-keepers.
- 2. Compensate for their non-participation in the events the records report by
conceiving of the record itself as the event.
Various constituents may need to be convinced about the
authenticity of the digital records stored in the system. If principles and approaches
that have been developed over time for analog records can be adapted, the resulting
embodiments may increase the comfort level of constituents and customers.
Thus, several authenticity approaches from the analog environment
may be considered for certain example embodiments:
2.1.2 Preserving Digital Objects
- Documenting the provenance and full history of the record;
- Comparing the record to another (reference) copy;
- Comparing the record to a "script";
- Establishing and monitoring procedural and technical controls over the records;
- Comparing the records to organizational standards for authentic records;
Once considered the greatest challenge because of the fragility
of physical media, the technical aspects of preserving digital objects now are well
understood. As noted previously, meeting technical requirements is necessary but
not sufficient for preserving authentic records. For example, to preserve digital
objects, it should be possible to verify that the information system: stores the
right data properly, protects the stored data from alteration or change, retrieves
all the right data and only the right data from storage, subjects the retrieved
data to an appropriate process, executes the process correctly, etc.
The nature of the digital object, or "digital informational
entity," being preserved includes a single, composite bit stream, the bit stream
representing the core content of the entity (e.g., the encoding of a document, data,
or a record), including all structural information required to constitute the entity
from its various components, wherever and however it may be represented. Component
bit streams may represent all necessary contextual or ancillary information needed
to make the entity meaningful and usable. Each component of the bit stream may be
verified in the five technical areas outlined above.
2.1.3 Preserving Authentic Digital Records
There is a growing consensus that authenticity of records
is a judgment - a continuum - rather than a binary, yes-or-no choice. Two of the
major claims involve establishing the identity of the records and demonstrating
their integrity. Identity refers to the attributes of a record that uniquely characterize
it and distinguish it from other records. The identity of a record refers to its
provenance, author, addressee, writer, date, action or matter, and archival bond
(relationship to other records). Integrity of a record refers to its soundness (e.g.,
its condition is unimpaired) and completeness (e.g., it possesses all the necessary
These factors raise questions regarding what constitutes
the "essence" of a record, or a record's "necessary parts." For example, there are
some components of a record that can be lost without compromising its substance
and the ability to verify its authenticity over time, and there are other components
of a record, the loss of which would be equivalent to the loss of the record. Some
examples of the latter may include the color in a map or columns in a table.
Certain example embodiments may follow four steps given
the above. First, identify for each type of electronic record produced by an organization
the components that ensure its authenticity over time. Second, assess whether those
components that are not visible to the user can be made visible and stabilized by
linking them inextricably to the intellectual form of the record. Third, determine
whether, in the cases in which the component could not be made visible and stabilized,
it would be possible and advisable to move the records in question to a non-digital
form (e.g., microfilm). Fourth, adopt self-authenticating and well-documented procedures
for migration and an uninterrupted line of physical custody.
There are a number of "boundary conditions," which may
include situations or contexts with identifiable risks of changing the records.
Some examples include processing (e.g., any processing entails some risk that the
records will be altered), migration (e.g., there are risks whenever a technological
dependency is altered or removed or the technology itself is changed), and changing
physical and/or legal custody (e.g., risks are present whenever records change custody).
Therefore, during any migration or transformation, an archives
system may need to make certain that the essential components of the record are
not compromised. The authenticity of a preserved electronic record can be certified
only if an archives system can show that none of the specific authenticity requirements
applicable to the record were violated.
2.2 Illustrative Approach to Demonstrating, Asserting, and/or
2.2.1 Introduction and Assumptions
As noted above, authenticity is a judgment that involves
levels of certitude rather than a binary yes/no decision. Authenticity applies to
records and aggregates of records, not to bit streams; it is a determination about
conceptual objects, not logical or physical objects. Preserving accurate bit streams
is necessary but not sufficient for preserving authentic records. Authenticity involves
policy decisions that are likely to be tested by the courts; thus, the archives
system may be flexible enough to permit implementation of different policies for
authenticity now and in the future. The original bit stream received from the institution
or donor may be preserved in an unaltered form. The bit stream in itself does not
constitute the authentic record. The approach of certain example embodiments for
maintaining the conceptual record may involve transforming the information to a
different bit stream. It will be appreciated that authenticity can be strengthened
or weakened by users or system actions. This includes the transferring institution
or donor, record administrators, archivists, and/or the system services.
2.2.2 Steps for Demonstrating, Asserting, and/or Providing Authenticity
The approach for preserving authentic digital records may
be broken down into five steps or components in certain example embodiments:
- 1. The archives system may receive reliable digital records from institutions,
such as federal agencies or other donors.
- 2. As part of the templates for records, the archives system may develop default
authenticity requirements for different type of records.
- 3. Prior to ingest of a particular body of records, the archives system may
develop a Preservation and Service Plan that either accepts or modifies the default
- 4. Throughout the rest of the records' lifecycle after ingest, the archives
system may preserve an accurate bit stream.
- 5. Throughout the rest of the records' lifecycle after ingest, the archives
system may be able to produce copies of the digital record (and associated metadata)
that can be used to judge the continuing authenticity of the records. Although ultimately
an archivist must judge authenticity, the archives system's large volume of records
will require computer-implemented methods to check specific features of the record
that give an indication of authenticity. Human assessment also could be applied
to sampled records as part of a quality control process.
Details for each of these steps follows.
126.96.36.199 Step 1: Reliable Digital Records
As defined above, "reliability" is a factor of the creation
and maintenance of the records by the originating institution. As such, reliability
ultimately may be outside the scope of the archives system. Nevertheless, the archives
system may address reliability because it will be of long-term interest to users.
For example, there are a number of policy options for the
administrator of an archives system in the area of reliability, such as:
- Excluding reliability as a factor when accepting records for ingest.
- Requiring originating agencies submitting records to certify the reliability
of their own records before they are accepted for ingest.
- Establishing reliability requirements for agency records and have the archives
system certify agency compliance before accepting records for ingest.
While the archives system will be flexible enough to implement
these or other policy decisions about reliability, any one option may be selected
as the default. For example, as a step in the ingest process, originating institution
or donors may be required to certify the reliability of the records.
188.8.131.52 Step 2: Default Authenticity Requirements
Default records templates may be indicative of policy options
for defining authenticity requirements. Authenticity statements and strategies may
be based on and/or relate to, for example, provenance, audit trail, completeness,
metadata, normative copy, digital recipe, suitability for purpose, and/or the like.
With respect to provenance, complex digital objects may
require maintenance of unbroken provenance relationships among components of the
object. The archives system therefore may capture all available source(s) and/or
provenance information about the record and its digital components at the time of
ingest. The archives system also may maintain an unbroken provenance for the records
Audit trails may indicate the series of transformations
that has brought a particular document to the desktop, and such a trail ultimately
may lead back to the creation of the initial document (or at least back to a version
that we had independent reasons to trust as authentic). The archives system may
have the capability to capture information about interactions with and changes to
a record, to ensure that an audit trail exists. A predetermined policy may indicate
what should be captured as part of the audit trail.
Completeness of records is another concern. Accordingly,
a policy regarding incomplete records (or aggregates of records) presented for ingest
may be established. Among the options are to ingest records that are known to be
incomplete and document this fact, refuse to accept incomplete records, etc. To
this end, the components of a record (or aggregate of records) either before or
at the time of ingest may be defined. The archives system may be able to capture
these components at ingest and/or demonstrate at any time in the future that the
records remains complete.
Metadata may begin by documenting the content, structure,
context, presentation, and/or behavior of the record. The metadata also may include
documentation for any changes or transformations made to the records. Ultimately,
using metadata as part of an authenticity approach may mean being able to compare
a record to what its metadata says it should be. There are at least two specific
metadata elements that can be considered for an authenticity policy: a unique identifier
(e.g., each record may have a persistent unique identifier that can be used to distinguish
it from other records) and a digital hash (e.g., the archives system may generate
a digital hash for each record and, as part of the records catalog, this hash may
be used to identify potential duplicate records). The hash algorithm also may be
re-generated at any time to verify that the record in question matches the original
hash value captured in metadata.
One authenticity approach involves comparing an object
in question to a known "reference object" or "normative copy." Comparing an object
in question to a normative copy is easy to do with editions of a book, but more
challenging with digital records. One approach for digital records is to create
and capture a normative copy at ingest for future comparison. In an embodiment,
this might work as follows:
Creating a normative copy, however, adds complexity: The problems of preserving
the normative copy are the same as those of preserving the digital records themselves.
A record is a conceptual object, requiring software and hardware to process the
bit stream. If it were straightforward to preserve in working condition the original
software for the "normative copy," then the whole digital preservation issue would
be much simpler. In one embodiment, a normative copy of a digital record may be
created at ingest and may be made available for comparison throughout the rest of
- Determine if a normative copy should be created and captured for each record
or aggregation of records. The normative copy might be a sample record that represents
the entire aggregate of records.
- Determine the type of normative copy to be created and captured. For example,
a static TIFF file could be created at ingest to document the presentation of a
- Implement the policy by creating and ingesting the normative copy
- In the future, a version of a record always could be compared to the TIFF normative
copy captured at ingest.
A "digital recipe" or set of instructions when making presentations
about persistent preservation may be implemented. The original object might be preserved
by breaking it into its component parts, and storing the parts and the assembly
instructions in a human-readable container. To this end, the electronics archives
may preserve a set of metadata instructions (e.g., a digital script) for recreating
the digital record.
Authenticity may be determined, in part, by suitability
for some purpose. A "suitability strategy" that uses various tactics to specify
and test whether an informational entity fulfills a given range or purposes or uses
may be implemented. Rothenberg's "suitability strategy" has two steps:
Jeff Rothenberg, "Preserving Authentic Digital Information." Pages 51-68 in
"Authenticity in a Digital Environment." May 2000. Council on Library and Information
. Available at: www.clir.org/pubs/abstract/pub92abst.html.)
- Establish authenticity principles for various domains or disciplines that will
make it possible to define authenticity in functional terms from the expected range
of uses. For example, the following sequence of decreasingly stringent principles
is stated in terms of the relationship between a preserved digital informational
entity and its original instantiation: same for all intents and purposes, same functionality
and relationships to other informational entities, same "look and feel," same content
(for any definition of the term), same description, etc.
- Derive a set of authenticity criteria (from each authenticity principle) to
serve both as generators for specific preservation requirements and as conceptual
and practical tests of the success of specific preservation techniques.
The archives system may permit the definition of principles
and criteria related to suitability for purpose. Any subsequent output from the
archives system then may be assessed against the suitability of purpose criteria.
184.108.40.206 Step 3: Ingest and Preparation of Preservation and Service
Prior to ingest, an archivist may first decide which reliability
policy option to apply to the specific records (optionally excluding reliability
as a factor, requiring the institution to certify the reliability of the records,
establishing reliability requirements for institution records and having institution
compliance certified before accepting records for ingest, etc). The archivist may
then review the default authenticity requirements for the records and modify the
requirements, if necessary. Finally, the archivist may prepare the Preservation
and Service Plan that includes future assessments of the authenticity of the records
periodically or on an ad-hoc basis.
220.127.116.11 Step 4: Accurate Bit Stream
As a condition for the authenticity of the records, the
archives system may accurately preserve the bit streams ingested into it, for both
content and metadata. This technical preservation may use standard information processing
techniques (such as, for example, hash algorithms) to demonstrate that the bit stream
18.104.22.168 Step 5: Authentic Copies of Records
At any point during the lifecycle of the record, an archivist
may be able to create a copy of a digital record from the archives system and compare
this output to the original (or subsequent) authenticity requirements as specified
in the Preservation and Service Plan. On the basis of this comparison, the archivist
may be able to "authenticate" and/or "certify" the copy.
3. Example Implementations of Authenticity
This section identifies several illustrative components
for establishing authentic electronic records. Of course, it will be appreciated
that such components are provided by way of example and without limitation. Moreover,
the components may be combined in various combinations and sub-combinations to achieve
yet further embodiments.
3.1 Components of Authenticity
Establishing authenticity involves two related sets of
components. The first set defines a record. Archival theory states that records
have three fundamental aspects: content, structure, and context. In the Society
of American Archivists (SAA) Glossary of Archival Terminology, the terms are defined
- 1. Content is the intellectual substance of a document, including text, data,
symbols, numerals, images and sound.
- 2. Structure is the manner in which elements are organized, interrelated and
- 3. Context is the organizational, functional and operational circumstances surrounding
materials' creation, receipt, storage or use and its relationship to other materials.
There is also a set of components relating to the ability
to assess authenticity of electronic records as their physical and digital manifestation.changes
over time. This includes three components:
- 4. Essential Characteristics are defined as those properties/characteristics
of electronic records that must remain unchanged through transfer, ingest, storage
and presentation or output of records.
- 5. Provenance is defined by SAA as "the origin or source of something: information
regarding the origins, custody and ownership of an item of collection." Provenance
maintains custodial history including any processing on digital files that hold
- 6. Integrity ensures the bit level integrity of data files and the relationships
between groups of digital files that, in aggregate, hold record material.
Each of these components and subcomponents will now be
discussed in greater detail.
Content, in this case, signifies the information or meaning
conveyed by a record. Mechanisms may be in place to ensure that the information
and meanings are not lost. Preserving record lifecycle data including the original
order helps to convey the meaning of the records.
The structure of a record within the archival context identifies
the relationships between the documentary materials, files or items that constitute
a record. Maintaining the structure of records has been recognized as providing
for their understanding and value, and therefore to their authenticity. In the electronic
sphere, this presents new challenges because the relationships between data files
may define the informational content in the record. For the duration of a record's
life within ERA, for example, two levels of structure may be maintained - the structure
of records and the structure of data files. The structure of records based on a
classical hierarchy of Record Group / Series / File Unit / Item may be used to capture
records structure. This may help to support the archival bond. The data files structure
may also be captured as an adjunct to preserving the content of records.
The SAA defines context in general as "the organizational,
functional, and operational circumstances surrounding materials' creation, receipt,
storage, or use, and its relationship to other materials." The context relates to
the environment in which records were created and used. The ability to place records
in their context helps to convey understanding pertaining to their meaning and importance.
Both context in general and also specifically as it relates to encoded archival
context may be monitored. From an implementation perspective, encoded archival context
is a Document Type Definition (DTD) that is compatible with use of XML and extends
the creation of encoded archival description.
The term "essential characteristics" is used two ways in
the archival community with respect to electronic records. The first is to enumerate
the necessary conditions to establish authenticity based on the records within the
archives, and the second is to identify those aspects of the representation of the
electronic record that must be preserved to preserve information and meaning. When
used in this context, it is important to note that essential characteristics are
assigned to record types and not to the records themselves. A record that is of
a certain record type will have a certain set of essential characteristics associated
to it that may be preserved. Essential characteristics also may be ensured at the
record aggregate level (e.g., such as at a record series and not just at the record
type level). The archives system may need to be able to capture record types, determine
the correct essential characteristics for the records type, and associate the characteristics
with the records. As records are transformed over time, for example, a transformation
into a more persistent format, the essential characteristics of the record must
The provenance of a record refers to its origin, chain
of custody, and its custodial history. If the provenance of a bit-stream is in doubt,
its value as a record, and therefore its authenticity, may be invalidated. For an
electronic record within an archives system, the meaning of provenance may be extended
to include not only the origin of the data files and their custodial history, but
also the history of all actions taken on those data files. This includes making
different electronic versions which may be the basis for a representation of the
records in future.
Integrity includes fixity and provides the assurance that
the digital item has not been modified. Fixity of records ensures the stability
of the files in the archives by checking that a file is what it purports to be,
and that it has not been corrupted over time. Fixity, validation, and virus checks
are all part of the process to ensure the data integrity of the bit-stream. While
the original bit-level manifestations will not change, presentation of the bit level
manifestations may change. This means information about the transformations also
may need to be captured. The concept of integrity then may have to extend beyond
the bit-level integrity of the data files put into the archives. Integrity of electronic
records archives systems includes capturing and maintaining in a reliable manner,
all the derivations from the original data files and the nature of the processing
that created the derivation. This may help to ensure that processes that had been
approved for the purpose of archival preservation were applied to the data files.
Integrity also may be further strengthened by overall system
credibility, specifically the standard system processes and procedures used to process
files and records, along with Information Assurance principles followed by the system.
3.2 Exemplary Support Structure for Authenticity
Figure 6 is an illustrative support structure model that
provides an exemplary pictorial view of the elements useful for establishing authenticity
for the electronic records archives system, in accordance with an example embodiment.
This structure may help provide elements that will enable the archives system to
establish and maintain the authenticity of records within its archive. It will be
appreciated that the following elements may be used alone or in various combinations.
3.3 Implementing Authenticity
- Transferring Institution or Donor - provides reliable records that are set for
transfer using the ingest process.
- Standard Business Practices - provide the foundation for managing records throughout
- System Credibility - includes the design and development of the archives system
based upon custom and/or industry standard processes and procedures that govern
one or more of the following: requirements, design and development; integration
and test; configuration management; and quality assurance management. System credibility
may also be predicated on the implementation of information assurance controls and
the receipt of system "authorization to operate" based on the completion of Certification
- Components Related to Records and Archival Judgment are represented as grouped
pillars and include components of:
- o Records that include: content, structure, and context; and
- o Archival judgment of the records that includes: provenance, essential characteristics,
- Authenticity - is a judgment that involves levels of certitude and is based
on the foundational layers that lie beneath.
Given the above support structure model, the issue becomes
how to implement authenticity of records within the archives system. The layered
approach identifies a method to achieve a degree of confidence as to the levels
of certitude of authenticity. Within the ERA system, for example, a balance of human
and manual operations is conducted along with high speed system processes to ensure
that a large set of records are archived. If the support structure model is analyzed,
to attest to the authenticity of records, the entire archives system has to be credible.
This means that risk should not be assessed just at individual processes or for
archival users or records administrators. Instead, the entire system may be held
accountable for proving the authenticity of a particular record.
The following sections spell out the "what" and the "how"
of certain example implementations. The sections include:
- 1. Transfer from External Entity: this section addresses the lowest layer of
the archives system support structure model that ensures that reliable records are
sent from transferring institutions and they undergo a systematic ingest process.
Each of the steps within the ingest process is identified to illustrate how authenticity
components are addressed.
- 2. Standard Process for Electronic Archives: this section addresses several
exemplary standard business processes and the ability to implement this process
within the context of electronic records for long term preservation. A lifecycle
view of authenticity is presented that ensures that each component of authenticity
is defined and how these principles are implemented.
- 3. Archives System Credibility: this section addresses the archives system and
the standard processes used for system development. Its description includes information
assurance principles that ensure system accreditation and test verification to ensure
that authenticity components are implemented. It then addresses the pillars of the
support structure by presenting how the archives system addresses each authenticity
component based on the lifecycle view.
It will be appreciated that the techniques disclosed in
the following sections may be used individually or in various combinations.
3.4 Example Implementation for Transfer from External Entity
This section provides a description of how reliability
of records may be maintained as electronic records are transferred from the transferring
entity (e.g., institution) to the archives owner and how authenticity components
are addressed within the archives system ingest process.
3.4.1 Reliability of Records
A reliable record stands for the facts it contains - that
is, the record's content can be trusted. The reliability of a record generally depends
upon the completeness of the record's form and the control exercised over the process
of creation. A reliable record has authority and it can be determined who created
it, when it was created, how it was created, and the purpose for which it was created.
The originators of records (e.g., in this case, the transferring entity) may be
responsible for creating and maintaining reliable records, digital or otherwise.
One purpose of an archives is to preserve reliability over time, which archivists
generally refer to as "maintaining authentic records."
When judging the reliability of records, trustworthiness
is synonymous with reliability. In the archival literature, trustworthiness is often
defined in terms of reliability and authenticity. In the context of electronic records,
trustworthiness often implies that the system is dependable and produces consistent
results based on well-established procedures.
The archives system may address reliability because it
will be of long-term interest to users of the records. Furthermore, in the case
of the ERA example, reliability spans multiple stakeholders that include the different
initiating government agencies that transfer their records to NARA for preservation.
Archives system services may be developed to be flexible
to handle differing reliability criteria for digital records. For example, digital
records may be accepted from the transferring entities "as-is" and maintain reliability
as a factor as records are accepted for ingest.
3.4.2 Transfer Process
The archives transfer process may include electronic transmission
or physical media shipping of electronic records from transferring entities. The
electronic transmission of a transfer package may include, for example, 2-Factor
or Strong Authentication between the transferring entity and archives for the connection
and transmission. The transfer protocol may confirm successful transmission of all
bits of data. In the event of a failure to successfully transmit the transfer package,
the transfer protocol may retry the transmission.
In certain example embodiments, data files both in and
not within a defined transfer package may be accepted. For those data files that
are contained within a defined transfer package, a digital hash may be generated
during the creation of the package. This will provide reliability of the records
when the package is opened inside the archives system during ingest processing.
Non-packaged data may have integrity asserted at the time of ingest processing.
Physical media shipped to the archives system may not have any additional authenticity
and/or reliability during the transfer process. Optionally, an Interface Control
Document (ICD) that engages the external transferring entities to instill an orderly
transfer process may be provided.
In one example embodiment, according to SF 258, "Agreement
to Transfer Records to NARA," the transfer of records is in accordance with U.S
Code that states that custody of the records becomes the responsibility of the Archivist
of the United States at the time of transfer of the records. The Archivist may destroy,
donate, or otherwise dispose of any containers, duplicate copies, unused forms and
non-archival printed material. The Archivist will use the General Records Schedule
and any applicable records disposition schedule of the transferring agency to dispose
of non-archival material.
3.4.3 Ingest Processing
The ingest process may combine the human interaction that
is necessary for records processing along with the high-speed ingest process to
transmit large volumes of records. Figure 7 shows illustrative business workflow
processes and steps to implement authenticity during ingest processing of transfers
in accordance with an example embodiment. The business processes that the archives
system conducts may include, for example, the following:
Of course, it will be appreciated that some or all of these steps may be performed
in different orders and that some or all of these steps may be combined into fewer
steps in certain example embodiments.
- 1. The initial step on the archives system side is to ensure that the transfer
media that contain the records have passed initial visual inspection and the system
records processor places the media into a temporary staging area.
- 2. The system records processor then ensures that the media are mounted for
upload into the system. The system then performs scans that include security and
integrity checks as automated processes.
- 3. The system then conducts validation checks to ensure that the electronic
bit-stream that relates to records is intact.
- 4. The files for the records are stored within managed storage, and the files/
records are made available for searching based on the use of an electronic asset
- 5. The system ensures that verification processing is conducted manually on
the files/records and the records processor resolves issues with the external transferring
- 6. The system then provides its users with notification of the records that
are stored for preservation and persists the necessary metadata for the records
Now that the system ingest processes are described, the
authenticity components can now be cross-referenced to ensure that authenticity
of records is supported. Figure 7 also provides a set of steps in alphabetics, that
correlate with ingest processing tasks.
Again, it will be appreciated that some or all of these steps may be performed in
different orders and that some or all of these steps may be combined into fewer
steps in certain example embodiments.
3.5 Example Implementation for Standard Process for Electronic
3.5.1 Implementation of Standard Business Practices
- A. When the transfer media are placed into the temporary staging area, the archives
system validates the Records Processor via a 2-Factor Authentication. This identification
and authentication activity is logged.
- B. When the system uploads the electronic media into temporary working storage,
this system activity is audited and logged.
- C. During the scanning and validation process, the system conducts virus and
security restriction scans. To preserve integrity, the system activity is logged
and the Virus/SAR scan version is logged.
- D. Intelligibility processing is conducted within the validation process that
includes ensuring that digital files that contain the records can be opened and
used. An integrity seal (e.g., hash algorithm) is applied to the file. This system
activity is audited and logged.
- E. During the validation process, the system validates the contents of the file
against the transfer documentation from the external agency. The agency header information
that identifies the context for the record is retained and the system activity is
- F. The validation process includes fixity checks. This includes record validation
against the disposition agreement and other related business objects. The system
retains item characteristics and the system activity is logged.
- G. The record is placed in managed storage that includes persisted information.
The system generates lifecycle metadata that supports the searchability of the record
and this information is kept within the electronic asset catalog.
Archives systems according to certain example embodiments
may be designed based on, for example, the foundation of standard NARA business
policies and processes. NARA has been a recognized leader in the development of
policies and processes in archives and records management. The archives system may
be flexible enough to implement both current policies and new ones that are developed
as the archives system matures.
In terms of admissibility of records into evidence, courts
tend to admit records that are created in the "normal course of business" by dependable
human and machine processes. This standard also may be applied if and when an archives
system is tested in the courts.
In another example, NARA has formed a Business Practices
Integrated Product Team (BP IPT) that is defining NARA's business policies and processes
that would then be codified into the ERA system. This concrete expression of policies
and procedures may help to defend records in ERA. This BP IPT is putting together
a baseline to define the system process in the current and future environments.
Subsequent section(s) provide details on illustrative archives
system test processes that include rigorous test procedures to demonstrate that
policies and processes are expressed in dependable system actions.
3.5.2 Lifecycle View of Authenticity
The archives system may draw upon the archival concept
put forth by the Open Archival Information System (OAIS) reference model. The archives
system may extend the OAIS reference model and map the model's archival functions
to system-level service packages, and/or tangible components of the archives system.
A lifecycle view can now be defined that allows authenticity of records to be attested
based on the overall records lifecycle.
Figure 8 steps through an illustrative lifecycle view by
identifying each activity that impacts authenticity. The lifecycle begins as records
go through the process of appraisal all the way to being archived within the archives
system. The activities are numbered based on the flow of the archives system. The
archives system design approach is entwined within this lifecycle view, and the
textual context is provided for each activity below.
3.5.3 Archives System Design Considerations
- 1. Records Scheduling
- a. Establishes that records are permanent and will be transferred to an archives.
This includes descriptions of context and purpose in appraisal reports and series
descriptions in schedule items.
- 2. Transfer
- a. The secure transmission of the electronic records to the archives system.
- b. Comprises metadata from transferring entity that includes the record structure.
- c. Establishes proof of integrity of the data files from transferring entity
- 3. Ingest Processing
- a. Unpackaging and initial processing of transferred files.
- b. Integrity seal applied to data files.
- c. Captures metadata, including record structure, from transferring entity.
- d. Captures lifecycle data in respect to any processing on the data files.
- e. Extracts additional metadata, and associates to templates - notably data
- 4. Preservation Planning (which may occur prior to or after transfer to archives)
- a. The archival determination and recording of essential characteristics that
must be preserved.
- 5. Description
- a. Creation of description and additional metadata to provide context for records.
- 6. Assessment (e.g., of digital adaptation processing and presentation)
- a. Archival assessment of the capability of adaptation processing to preserve
- b. Archival assessment of the capability of presentation functionality to express
the essential characteristics that have been preserved.
- 7. Preservation Processing
- a. Selection of digital adaptation processing that best preserves essential
- 8. Presentation functionality
- a. Ability of presentation functionality to express essential characteristics.
Several design considerations may be taken into account
when providing for authenticity of records within the broader archives system design.
Design consideration may include one or more of the following exemplary considerations:
Of course, it will be appreciated that the same are provided by way of example and
22.214.171.124 Archival vs. System Assessment
- Ability to receive reliable digital records from institutions or donors;
- As part of the templates for records, development of default authenticity requirements
for different types of records;
- Use of archival judgment to assess the capability of processes that create new
digital versions of record material, and presentation technologies that are used
to create renditions of the records;
- Use of National Institute of Standards and Technology (NIST) approved mathematical
algorithms to establish the bit-level integrity of content of digital files and
provide the capability to assess the bit-level integrity of data files into the
- Throughout the rest of the records' lifecycle after ingest, ability to produce
copies of the digital record (and associated metadata) that can be used to judge
the continuing authenticity of the records; and/or
- Functionality to attest to the authenticity of records being based on incremental
Both archival judgment and system processes embedded into
the archives system may play a role in determining authenticity. The large volume
of records may require computer-implemented methods to evaluate the conditions for
authenticity of records. Human assessment may be applied to archives system processes
that impact authenticity using sampled records as part of a user acceptance testing
process that can serve as quality control. Computer-implemented processes may be
incorporated within the archives system based on its increment-based release of
functionality. These processes may codify business processes into system orchestrations
and controls that are built into the system.
126.96.36.199 Use of Templates
Templates that define the essential characteristics of
record types may be developed. For example, according to NARA, a template is a set
of specifications about a type of electronic document, record, donated material,
or an aggregate of such electronic documentary materials. Such templates may provide
flexibility and extensibility to the architecture and may also provide a mechanism
for the system to evolve and adapt to changing organizational needs.
Within the lifecycle view, part of the appraisal process
of electronic records may include confirming the template that should be applied
to a body of material destined for the archives. The template may be updated as
appropriate for the material covered by a specific schedule item. Templates also
may be applicable throughout the archives system records lifecycle.
188.8.131.52 Metadata Management
Metadata may be captured and/or generated within each activity
that impacts authenticity within the records lifecycle. The archives system may
have an extensible concept of metadata, which includes lifecycle data, description,
and templates, that will bind templates, and contextual, descriptive, and provenance
information to physical objects (e.g., data files) and conceptual objects. This
metadata may be available for presentation along with records to assist in establishing
The archives system may incorporate the design for an Asset
Catalog, which may hold an entry for every physical object (e.g., data file) and
for all conceptual objects (e.g., record series, collection, etc.). The design of
the asset catalog entries may save the structure of conceptual arrangements and
their associated physical objects such that the structure of records is persisted.
The asset catalog may provide the binding between the metadata of the record and
the data files that contain records stored within the archives.
Figure 9, for example, is a high-level overview of an illustrative
system. More particularly, Figure 9 is an extremely large scale computer storage
system 1900 in accordance with an example embodiment. An asset catalog 1902 may
comprise a plurality of asset catalog entries 1904 stored according to at least
one schema and corresponding to a plurality of assets 1908. A storage architecture
1906 may be capable of storing the plurality of assets 1908, with the storage architecture
1906 comprising a storage locator 1910 and a federator 1912 (and, optionally, an
object identification service 1914). An item identification scheme may be capable
of providing identifiers to reference, locate, and/or access said assets 1908 and/or
said asset catalog entries 1904 stored in the asset catalog 1902 in the storage
architecture 1906. The computer storage system 1900 may be scalable essentially
without limitation while maintaining asset storage and retrieval flexibility and
substantially obsolescence-proof survivability of assets. Optionally, a search/access
client 1915 also may be provided. Of course, it will be appreciated that the example
embodiments shown and described in connection with Figure 9 are provided by way
of example and without limitation.
184.108.40.206 Testing for Essential Characteristics
Detailed information regarding the essential characteristics
for records per record type and the criteria or process being used when employing
archival judgment to determine the authenticity of records may be used to develop
test criteria associated with archival judgment and the evaluation of essential
characteristics of records.
3.5.4 System Processes for Implementation
This section provides illustrative archives system processes
that step through the lifecycle view of authenticity and capture how authenticity
components are fulfilled.
220.127.116.11 Records Scheduling
Certain activities for the record scheduling step may include,
for example, capturing details of context and purpose in series descriptions (Transferring
Entity); capturing details of context and purpose in appraisal reports; and, defining
essential characteristics of the records. The archives system level packages attributed
to this function may include Records Management and Preservation. The components
to verify authenticity of records may include, for example:
18.104.22.168 Transfer to Archives
- Content - summary of content at record series level;
- Context - provides basis for understanding use of records in original context;
- Essential Characteristics - records are associated to a record type template
that includes the definition of the essential characteristics of these records;
- Provenance - establishes origin of records by agency and unit, may define custodial
plan for records prior to transfer.
The primary activities for the transfer to archives step
may include, for example, records transferred to physical custody; ensure and verify
use of legal transfer instrument; capture metadata (on the part of the Transferring
Entity and/or archives system); capture arrangement and original order (from the
Transferring Entity); and establish bit-level integrity (by the archives system).
The archives system package attributed to this function
may include Transfer/Ingest. The components to verify authenticity of records may
include, for example:
22.214.171.124 Ingest Processing
- Content - captures metadata from agency which may include content information;
- Structure - captures arrangement of data files and purported original order
- Context - captures metadata from agency which may include context information;
- Provenance - record of transfer occurrence establishes proof of provenance from
agency, and establishes physical control of records, baselining, for example, custody
of records; and
- Integrity - establish baseline for bit-level integrity of the data files.
The primary activities for the ingest processing step may
be to ensure, for example, that data files are verified, record type is verified,
and/or that records are written to archives. The ERA system package attributed to
this function is Transfer/Ingest. The components to verify authenticity of records
may include, for example:
126.96.36.199 Preservation Planning
- Structure - structure for records and data files is persisted in asset catalog
entries. May extract additional metadata from data file headers that assist in understanding
data file structure(s).
- Essential Characteristics - determines the data type of the data files, which
provides a relationship to a data type descriptor that will be used in preservation
processing and which defines any initial processing that must occur prior to writing
data files to the archives (such as extracting files from a composite file).
- Provenance - adds a series of lifecycle events that represent verifications
performed on data files (virus scan, access restricted material scan).
- Integrity - validates the bit-level integrity seal applied prior to transfer
on data files, and validates all files are received.
The activities' associated with the preservation planning
step may help to ensure archival determination of essential characteristics that
must be preserved. This may occur prior to or after transfer. The system package
attributed to this function is Preservation. The components to verify authenticity
of records may include, for example:
188.8.131.52 Archival Description
- Content - ensures information and meaning will be preserved through the definition
of essential characteristics;
- Structure - may include aspects of structure; and,
- Essential Characteristics - defines the essential characteristics to be preserved.
One activity for the archival description step is to ensure
creation of description and additional metadata to provide context for records.
The system package attributed to this function is Records Management. The components
to verify authenticity of records may include, for example:
184.108.40.206 Assessment of Digital Adaptation Processors and Presentation
- Content - provides informational aids (various notes) to assist in understanding
the information and meaning in the records;
- Structure - provides additional metadata that aids in establishing structure
of the records;
- Context - provides additional metadata that aids in establishing context of
the records; and,
- Provenance - may add additional information in respect to the origin and/or
chain of custody of the records.
The following items may be addressed by an archivist: archival
assessment of the capability of adaptation processing to preserve essential characteristics,
and archival assessment of the capability of presentation functionality to express
the essential characteristics that have been preserved. The activities associated
with this assessment step may help to develop digital processing functionality to
create more persistent formats for data files; create and/or identify technologies
to present the persistent data files; and/or assess the degree to which the digital
processors and presentation technologies preserve defined essential characteristics.
The system package attributed to this function is Preservation / Dissemination.
The components to verify authenticity of records may include, for example:
220.127.116.11 Preservation Processing
- Content - determines the manner in which content will be presented to users
- Structure - reflects the structure of the records in presentation to a consumer
of the records; and,
- Essential Characteristics - expresses the essential characteristics that have
been defined, to some degree, and determines the degree of fidelity of that expression.
One activity for preservation processing step may help
to ensure selection of digital adaptation processing that best preserves essential
characteristics. The system package attributed to this function is Preservation.
The components to verify authenticity of records may include, for example:
18.104.22.168 Presentation Functionality
- Content - determines which digital adaptation processors will best preserve
the information and meaning of the records by ranking each in terms of how well
it preserves the essential characteristics specific to the records being processed;
- Structure - determines which digital adaptation processors will best preserve
the structure of records;
- Essential Characteristics - as discussed above, this preservation processing
step is to address essential characteristics; and,
- Integrity - when using original data files, this validates the integrity seal
on those data files.
Activities associated with the presentation functionality
step may help to ensure that records are presented to users (the step may involve
presenting more persistent formats), and may help to associate data types to presentation
technologies, providing information on how particular presentation methods support
authenticity. The ERA system package attributed to this function is Dissemination.
The components to verify authenticity of records may include, for example:
3.6 Example Implementation for Archives System Credibility
- Content - determines how the consumer of a record will experience that record;
- Structure - determines how the consumer of a record will experience the structure
of a record; and,
- Essential Characteristics - determines which essential characteristics will
be expressed in the presentation of the record and the fidelity of that expression.
This section addresses the system credibility layer within
the records archives support structure for authenticity that incorporates use of
Information Assurance controls and adherence to standard processes. This credibility
rests on implementing, for example, information assurance controls in accordance
with industry standards and system certification and accreditation, standard business
processes that include quality assurance and configuration management, integration
and testing of the archives system that include component testing and end-to-end
testing of system level functionality to ensure the system performs as expected,
and/or operations and support processes. A description of each of these processes
3.6.1 Information Assurance Considerations
One aspect in ensuring the authenticity of records is to
adhere to Information Assurance (IA) controls that address the application of IA
protections in support of the archives system. The archives system may be accredited
to ensure that security requirements stated within policy documents are met. A security
Risk Assessment may be performed to determine which security controls are needed
to provide the requisite assurance that the system is adequately protected.
22.214.171.124 Policy Guidelines
Information assurance is the application of policies, processes,
and procedures in a defense-in-depth posture to support confidentiality, integrity,
and availability of information systems. NIST has established a series of guidelines
to facilitate the implementation of IA protections for information systems. These
protections are embodied as mandatory, minimum, security requirements in Federal
Information Processing Standard (FIPS) 200, Minimum Security Requirements for
Federal Information and Information Systems. These seventeen requirements are
part of the ERA system accreditation and are categorized in Table 2, below.
126.96.36.199 Information Assurance Principles Relating to Authenticity
Security Risk Assessment
System and Services Acquisition
Certification, Accreditation, and Security Assessments
Physical and Environmental Protection
System and Information Integrity
Awareness and Training
Identification and Authentication
Audit and Accountability
System and Communications Protection
The five general IA principles may be applied to the specifics
of the archives system to support the authenticity of records. The five core IA
- Availability - the state where information is in the place needed by the user,
at the time the user needs it, and in the form needed by the user.
- Identification and Authentication - process to recognize an entity, coupled
with a means of verifying an individual's authorization to receive specific categories
- Confidentiality - assurance that information is not disclosed to unauthorized
persons, processes, or devices.
- Integrity - quality of an IT system reflecting the logical correctness and reliability
of the operating system; the logical completeness of the hardware and software implementing
the protection mechanisms; and the consistency of the information structures and
occurrence of the stored information.
- Non-repudiation - the method by which the sender of information is provided
with proof of delivery and the recipient is assured of the sender's identity so
that neither can later deny having processed the information
Table 3 relates the general IA principles to the authenticity
of records in the archives system.
Implementation Relating To Authenticity
Not relevant to Authenticity
Identification and Authentication
This applies to archivists and records administrators and transferring systems
that need to be authenticated within the archives system. The requirement helps
ensure that Transferring Entities are who they claim to be.
This principle ensures that:
• Only authorized users have access to archived assets; incorporates
roles based access control
• Ensures that data transfers between sites are encrypted
• Data at rest is protected by restricting access to authorized users
who may only perform authorized functions
• Ensures compartmentalized security classifications
• The system implements handling restrictions of records as determined
by the transferring entity, donor or records manager
Proof that the digital asset has remained unchanged:
• The archives system ensures that an integrity seal is applied upon
ingest into the system via a content-based hash ID
• Implementation of roles-based access control ensures that only those
users who are authorized to alter / update / view / modify a record within the archives
system may do so.
Ensure that the originator cannot deny that the assets are theirs
• Audit trail that captures who did what to the record, and record
• Identification of a record's originator (e.g. human user, transferring
entity, or system user).
Based on the five IA principles, the archives system may
abide by NIST FIPS 200 security policy guidelines to ensure that security controls
are in place. This may apply to all of the security controls within the Identification
& Authentication family and the Access Control family, along with Integrity and
3.6.2 Standard Business Processes
This section provides a brief description of the adherence
to standard business processes, such as, for example, quality management and configuration
management in the development of the archives system.
188.8.131.52 Quality Management Considerations
Standards-settings organizations may approve quality management
standards that may, in turn, be used in connection with archives systems. For example,
Lockheed Martin Transportation and Security Solutions (TSS) has a full set of business
processes that are contained within its Business Process System Library (BPSL) that
have been determined to be compliant with ISO 9001:2000 and CMMI Level 5. These
LM BPSL processes may be used with and/or tailored for use with the records archives.
For example, the CMMI Level 5 rating certifies that the processes and procedures
in use are standardized, repeatable and predictable.
Within the BPSL, there are standard process categories
for: Company Level Management Processes, Program Management Processes, New Business
Processes, Engineering, Technology, & Operations Processes, and Business Operations
Processes. The following nine TSS processes have then been tailored for the ERA
Program for use with NARA: ERA Schedule Management Process (ERA-D20); ERA Configuration
and Change Control (ERA-F10-S004); ERA Engineering Process Compliance Matrix (ERA-E05-Compliance);
ERA Integrated Engineering process (ERA-E05-O1); ERA System Design Process (ERA-E30);
ERA Software Requirements Development (ERA-E35-S001); ERA Product Software Architecture
(ERA-E35-S002); ERA Adaptation Value Determination (ERA-E35-S004); and ERA Software
Development and Test (ERA-E40-S001-01). Experts in Quality Assurance may monitor
compliance with the above and/or other processes. They may represent an independent
voice reporting directly to a Program Manager.
184.108.40.206 Configuration Management Considerations
Configuration Management (CM) may cover a broad spectrum
of responsibilities. The tasks listed below identify CM responsibilities based on
standard CM processes, and can relate to upholding record authenticity.
- Coordinate CM functions to assure an integrated CM effort within the archives
- Establish Data Management process to establish and apply Data Management (DM)
standards to both deliverable and non-deliverable data;
- Develop and document ERA CM processes and standards;
- Implement and administer Change Management processes throughout the program's
- Implement formal control of the requirements specifications that define the
formal baselines through the Specification Management function of CM;
- Control the design and deployment of the equipment for the archives system through
the Hardware CM function;
- Control the formal builds and packaging of all developed software through the
CM Software Builds and Controls (B&C) function;
- Maintain and manage the configuration of COTS software through the Commercial-Off-the-Shelf
Software Builds and Controls (COTS SW B&C) function;
- Provide Product Control for program software products, including software license
- Control the formal test environment through the Test Configuration Management
- Provide information about the current status of the archives system through
Configuration Status Accounting;
- Conduct CM Configuration Audits during various steps through the program's lifecycle,
e.g., a Functional Configuration Audit (FCA) and a Physical Configuration Audit
- Track request for deviations and waivers for system requirements to completion;
- Coordinate and oversee the Program Trouble Reporting process through the Problem
Management function of CM.
Configuration management helps to establish baselines and
controls to baselines in several key areas. This may help to defend the integrity
of the archives system if challenged (e.g., in a legal dispute).
3.6.3 Testing Considerations
The testing program helps prove that the records archives
system is reliable. The testing program may help to "close the loop" on standard
business policies and procedures by proving that the system actually did was it
was designed to do.
220.127.116.11 Integration and Test
The Integration and Test (I&T) process may comprise the
tasks and activities needed to build and test the archives system incrementally
through different phases. The test approach may follow the same mature proven ISO
9001:2000 and Capability Maturity Model Integration (CMMI) Level 5 process. This
approach may be tailored to address the unique characteristics of the archives system,
including the Service Oriented Architecture (SOA), distributed deployment, external
interface requirements, security requirements, human factors specifications, and/or
the use of COTS products. Adherence to the processes leads to a carefully planned,
disciplined, rigorous, controlled, and structured integration and test program to
ensure a high quality, stable, usable system, satisfying high-level system requirements
in conjunction with demanding acceptance criteria.
I&T activities may starts with development testing at the
archives system development lab that includes: unit and string testing, software
integration testing, and external interface emulation and integration. The next
step is system integration testing that is conducted at a facility that mirrors
the archives system in production. This includes regression testing, system integration,
system testing, usability testing, accessibility testing, and performance testing.
The final set of testing is known as acceptance testing and this is done within
a customer acceptance test lab that includes product acceptance testing on a release
and increment basis, operational acceptance testing and installation acceptance
testing. Figure 10 depicts this illustrative Integration & Test Lifecycle.
18.104.22.168 Verification and Validation
One purpose of the I&T Lifecycle is to verify and validate
the archives system. Within this context, verification refers to the activities
performed to ensure that the system that was built accurately reflects the intent
of the system requirements, e.g., it provides confirmation that the correct system
was built. Validation activities confirm that the system that was built functions
as intended, e.g., the system performs activities correctly and returns the expected
results. These activities are performed on many levels (unit, software, system)
and from different perspectives (human factors, security, and performance).
Execution of the I&T Lifecycle may help to ensure authenticity
by verifying that the pillars of the archives system support structure for authenticity
mentioned above have been incorporated the software and system requirements that
codify this functionality. Test procedures and test cases incorporate elements to
demonstrate that the specified functionality has been built, is available to authorized
users, and functions as intended. Although the archives system credibility and the
necessary conditions for authenticity can be verified and validated, the determination
of the authenticity of a record still requires the application of archival judgment
via one or more predetermined standards. Implementation of these standards will
establish the archives system's ability to preserve authentic records.
22.214.171.124 End-to-End Testing
Standard business processes, which utilize the preservation
of authentic records as its fundamental precept, may serve as the foundation to
establishing the authenticity of the records within the archives system. Therefore,
end-to-end testing may be performed to establish the archives system's ability to
support standard business processes. End-to-End testing may be conducted at the
end of each increment. It may be comprised of a series of regression tests and system
level scenarios developed in conjunction with subject matter experts (SME) and based
on the output of the Business Process IPT. Each scenario may contain a mapping of
the steps to the conditions necessary for authenticity and therefore prove that
authenticity has been built into the system and that the system can produce authentic
3.6.4 Archives System Operations and Support Processes
Operations and support processes may be thought of as a
set of formally documented and repeatable actions or events required for achieving
specific goals. It is the means by which an operations team may provide consistent
and reliable support to the archives system, satisfy the requirements of the archiving
entity, and pursue continuous improvement and growth for the archive system. The
following illustrative operational processes may be required to provide consistent
and reliable support for the archives system:
4. Risk Mitigation and Incremental Authenticity Deployment
4.1 Program Risk Mitigation
- System Monitoring - the system monitoring process may provide continuous monitoring
and analysis of the archives system infrastructure. During system operation, periodic
checks can be conducted to ensure system and data integrity during processes such
as backup and restore.
- Backup and Restore - there are two methods for the backup and restoration of
the archives system that provide a safeguard against the loss of system data including
archival assets. A first method may be implemented in an automated manner by the
archives system that uses COTS backup and restore products. As a supplement to these
services, a manual backup and restore process provides an additional capability
that will be manually executed by SOC team members on an as-needed basis.
- System Problem Diagnosis and Repair - the system problem diagnosis and repair
process may provide for the management and tracking of all archives system infrastructure
issues and problems impacting the archives system.
- System Maintenance - the system maintenance process may outline how routine,
periodic, and preventative maintenance will occur for the archives system.
- Inventory Control - the Inventory Control Process may provide for the tracking
of all shipments of archives system materials, hardware, software, and supplies.
- Help Desk - the Help Desk Process may help manage and track all reported problems.
- Government Media Inventory Control - the Government Media Inventory Control
process may manage government media received at the ERA facility in a consistent,
- Request for Deletion of a Record - the Request for Deletion of Record Process
may provides the archiving entity the capability to designate, approve, and delete
records in the archives system in a consistent and predictable manner.
It will be appreciated that the embodiments disclosed herein
may help to provide program risk mitigation to the overall problem associated with
the authenticity of records. To address the overall question, a support structure
for the archives system that helps to establish authenticity that includes a combination
of system credibility measures and necessary authenticity components may be provided.
Authenticity may be provided in connection with electronic records. Custom and/or
standard processes may be used to address system accreditation and overall system
Three components help assess authenticity of electronic
- 1. Provenance: ensuring that records captured within the archives system can
be traced back to their origination.
- 2. Integrity: protecting the data within the system with information assurance
controls upholding the five principles that include: integrity, availability, confidentiality,
non-repudiation, and authentication and identification.
- 3. Essential Characteristics: making certain that the records continue to embody
their fundamental nature as determined by the archivists.
Achieving this requires a design that identifies the necessary
components for establishing authenticity, designing to ensure these conditions are
met, and ensuring that the system itself is reliable and credible.
4.2 Functionality Allocation to Archives System Increments
Functionality may be provided in distinct groupings over
time. This development strategy may contribute to overall system reliability because,
for example, each successive increment may be analyzed and/or certified as being
reliable and contributing to system reliability in the interim. For example, an
initial increment may provide:
One or more further increments may provide:
- Records Scheduling - create records schedule.
- Preservation Plans (limited) - record suggestions for essential characteristics;
the identification of essential characteristics is currently a work in progress
and so the functionality provided within the initial increment is limited.
- Transfer to Archives - capture available metadata from transferring entities,
capture available original order information, apply integrity seal.
- Ingest Processing - take physical control of records, establish lifecycle data
baseline, and validate integrity seal.
- Lifecycle and Audit Data - address deployed system processes to maintain provenance.
5. Exemplary Overview of Authenticity in an Electronic Records
5.1 Exemplary Definitions and Illustrative Aspects
- Digital Adaptation - creation of more persistent electronic formats for records.
- Archival Descriptions - providing additional lifecycle data that supports authenticity.
- Preservation Plans (enhanced) - support archival determination of essential
characteristics that must be preserved for permanent records.
- Preservation Processing - selection of digital adaptation processing that best
preserves essential characteristics.
- Presentation Functionality - present records to users in more persistent formats,
provide different data types that associate with presentation formats.
- Lifecycle and Audit Data - expanded support for added processing.
As used herein, the term "asset" may include any electronic
(e.g., digital) information archived in an archives system, and the term "electronic
record" may include a single conceptual object, which may be comprised of multiple
files, that is made or received by an organization or institution. An electronic
record is a type of electronic asset. A non-record asset may be information about
or derived from records. Authenticity applies to records, though elements of authenticity,
such as integrity, apply to all assets.
Certain example embodiments establish and/or maintain the
authenticity of records stored in an electronic archives system. The example systems
and methods generally may provide a comprehensive set of processes that achieve
new, higher levels of authenticity standards. One aspect of authenticity relates
to provenance, as described above, refers to the origin or source from which something
comes along with the history of subsequent owners (e.g., the chain of custody).
Provenance is a fundamental principle of archives in general, referring to the individual,
group, or organization that created or received the items, e.g., in a collection.
Another aspect of authenticity involves the Essential Characteristics of an electronic
record and, as described above, Essential Characteristics include those properties
and/or characteristics of electronic records that must remain unchanged through
transfer, ingest, storage and presentation or output of records (including preservation
processing). A record's essential characteristics should remain unchanged so that
there is no loss of the information content of the asset providing archival value,
which may be needed for authenticity judgment.
Essential characteristic parameters may be defined by record
type. It will be appreciated that essential characteristics of assets may change
over time for a given record type if it becomes apparent in the future that some
characteristic should have been captured or captured at a different standard, for
example. To deal with this problem, either the original formats have to be interpretable
forever, which means having to maintain an ever expanding capability (e.g., number
of software applications) ready to interpret every format ever archived, or else
original formats have to be adapted to modem, supported formats from time to time,
which risks losing unforeseen essential characteristics if these adaptations cannot
be lossless and inadvertently lose information needed for a characteristic subsequently
determined to be essential. Certain example embodiments support both approaches
and allow for a trade-off between these two approaches.
5.2 Exemplary Techniques for Establishing and Maintaining Authenticity
In certain example embodiments, a flexible set of processes
and interfaces, enforced through workflow and computer-implemented sub-processes,
may be combined to create a mechanism that meets a higher standard of electronic
records authenticity and which can be used to archive other institutions' electronic
records as well as an institution's own. For example, the processes may be flexible
in that they accommodate various situations that may arise, e.g., if the originator
of the materials to archive no longer exists (e.g., a defunct business) then not
all information about the records may be available.
Some or all of these sub-processes may combine to provide
new levels of authenticity in an archives system by providing the elements an archivist
needs to make a judgment of authenticity over the life of the record, including,
for example, ensuring asset integrity, establishing assets' essential characteristics,
and providing provenance.
5.2.1 Example General Workflow
These elements are provided by the following exemplary
general workflow. First, records and other associated electronic assets may be safeguarded
through their lifecycles. This may include providing mechanisms to manage aspects
of intended asset changes (e.g., record adaptations) and status, and also detecting
unintended changes to assets (e.g., through file integrity seal checks). Second,
associated context and structure may be extracted and preserved so that the meaning
of the records is known and their essential characteristics are defined and recorded,
including, for example, organizing records so that those created or received by
one records keeping unit are not intermixed with those of any other, as may be necessary.
Third, uninterrupted proof of custody may be maintained beginning as soon as possible
(e.g., establishing and preserving proof of the records' source) and for the life
of the record. Fourth, mechanisms may be established for defining and capturing
the essential characteristics of archived records, and for preserving these characteristics
in records as they may be adapted over the years from obsolete formats to new formats.
5.2.2 Example Sub-Process for Use with a General Workflow
The example workflow process described above may be used
in connection with one or more of the following example sub-processes. In general,
the sub-processes (or subroutines) correspond to acquiring records processes, ongoing
processes, and horizontal functions. It will be appreciated that the following sub-processes
may be made available via any suitable form of programmed logic circuitry.
126.96.36.199 Acquiring Records Processes
Records scheduling programmed logic circuitry generally
establishes the records to archive and collects information about the records. Such
records scheduling programmed logic circuitry may help to identify which records
are permanent and will be transferred to an archives. It also may collect available
initial information about the electronic records to be archived to plan their preservation
and begin to establish their authenticity (e.g., the early collection of contextual
information to establish chain of custody as early as possible thereby increasing
authenticity). Information collected may include disposition (e.g., retention time),
purpose, and context (e.g., structure, any existing appraisals, administrative and
custodial history), such as may exist. Early collection of contextual information
is part of bringing forward in the record lifecycle certain elements of the archives
processes to establish chain of custody as early as possible, thereby increasing
Preservation planning programmed logic circuitry may be
provided. Such preservation planning programmed logic circuitry may be useful to
establish the essential characteristics of records that must persist over time.
Scheduled records' essential characteristics should be preserved throughout the
archival process regardless of whether methods to protect these characteristics
exist. Transfer request programmed logic circuitry relates to a step in the legal
transfer of records during which time additional detailed information may be collected.
Such transfer request programmed logic circuitry may establishes an agreement to
transfer physical and/or legal custody of documentary materials, either for archival
or records center storage. It also may establish a standard record of the transfer
request at the point when certain details of the transfer are known, supporting
Package creation programmed logic circuitry may facilitate
flexible package creation, during which time additional attributes may be collected.
Such package creation programmed logic circuitry may help to package records and
associated information, e.g., documentary materials and additional metadata, for
transfer to the archival system. Metadata may include number of files, filenames
and attributes, who created, when created, how created, structure, description,
purpose, etc., at the source institution so as to establish chain of custody as
early as possible. Package creation also may involve a packaging tool that operates
in connected or disconnected mode. In certain example embodiments, a connected mode
may be more automated, whereas a disconnected mode may provide more flexibility.
Transfer programmed logic circuitry may provide for the
secure transmission of the electronic records to the archival system. This may include
documentary materials and transfer manifest.
Ingest extraction programmed logic circuitry may help to
collect metadata from transferred materials including essential characteristics.
Such ingest extraction programmed logic circuitry may provide for the unpackaging
of transmitted packages to access the individual files in the package and associated
metadata. This may include extracting certain metadata about the records' files,
which may further include extracting essential characteristics according to asset
type templates to capture the currently established essential characteristics for
an asset type while still accommodating the capture of new or unique characteristics
that may be identified for the transmitted assets. Ingest scanning programmed logic
circuitry may check for malware (e.g., viruses) and security classifications. Ingest
validation programmed logic circuitry may provide a comprehensive validation process
that includes checks that records are in accordance with previous steps. Such ingest
validation programmed logic circuitry may initiate a multi-level set of checks that
ensure the package received is not corrupt and is in accordance with records of
what is supposed to be transferred (e.g., according to business objects, such as
transfer agreements, records schedules, transfer manifests, legal transferences,
and/or disposition agreements). Ingest assignment of unique ID programmed logic
circuitry may assign an immutable, globally-unique identifier to each asset so that
it can be tracked and managed over time without any identification ambiguity. Ingest
integrity sealing programmed logic circuitry may help to ensure that asset corruption
is detected. Such ingest integrity sealing programmed logic circuitry may help to
derive a unique hash (e.g., number) for each record and/or for each file of each
record based on the content of the record and/or file. The hash does not need to
(and, in certain example embodiments, should not) change over the life of the record,
and may be used to prove the record has not changed over its life. This process
may be performed as soon as packaging occurs. The seal (e.g., hash numbers) may
be stored separate from asset (e.g., in the asset catalog) for protection. New record
versions may receive their own seal and may have different underlying files, but
the original record, including its files, always should be retained.
Preservation storage programmed logic circuitry helps to
ensure that records are stored according to handling restrictions and that access
controls are in place. That is, assets are stored (e.g., "bit streams" are preserved)
in accordance with any handling restrictions, and associated catalog entries are
created, capturing essential information used for authenticity, e.g., for tracking
the archives contents and capturing essential characteristic values and access and
handling controls. This may provide protection of assets in accordance with security
and privacy rules, preserve assets in accordance with their dispositions (e.g.,
retention times), including protection from premature deletion, may provide for
adaptation to new versions as electronic formats become obsolete, and eventually
delete or purge according to asset's disposition and with appropriate safeguards
to ensuring purging is still valid.
188.8.131.52 Ongoing Processes
Accommodations may be made for ongoing authenticity judgment
processes. Such accommodations may include, for example, workflows to automate and/or
enforce authenticity judgment processes, the checking of integrity seals, reporting
on chain of custody data, asset activity logs, and other data, all for the purpose
of supporting subsequent and ongoing integrity checks and archivists' viewing of
this information for authenticity judgment purposes.
Accommodations also may be made for ongoing preservation
and dissemination of assets. Such accommodations may include, for example, identifying,
capturing, and implementing security, privacy and handling restrictions, including
information assurance mechanisms (e.g., authentication and identification, confidentiality,
integrity, and non-repudiation), search metadata, and records' essential characteristic
values, to support subsequent asset preservation and dissemination. For preservation,
this may include accommodation for establishing new certified digital adaptations
of assets, e.g., modem asset formats that maintain essential characteristics, which
may include matching assets to digital adapters according to measures based on essential
characteristics, to derive modem formats of assets before they become obsolete,
and other asset versions, such as redacted assets. Dissemination aspects may support
authenticity, for example, by protecting assets, by accurately and completely rendering
assets, and by providing "findability" to ensure that any records competing for
authenticity can be known to the archivist to make a proper authenticity judgment.
Also, ongoing preservation processes may implement mechanisms to avert obsolescence
by migrating assets to modem formats without jeopardizing authenticity.
184.108.40.206 Horizontal Functions
Information assurance controls may be provided throughout
all processes and on all interfaces. In particular, all interactions (e.g., transfer)
with respect to the archives system may include information assurance controls (e.g.,
may include two-factor authentication with external institutions and access controls
internally) in accordance with security and privacy rules. Also, all actions on
assets may be tracked and made available for authenticity judgment purposes. That
is, all activities performed on assets may be logged to support subsequent reporting
in support of provenance. Log data may be added to archival storage as an asset.
Log record search keys may be added as metadata for the corresponding assets in
archival storage or individual log records may be added as assets in their own right
and explicitly linked to corresponding assets via the mechanisms of the asset catalog.
5.2.3 Additional Features and Benefits of Certain Example Embodiments
Certain example embodiments provide for a more comprehensive
asset lifecycle, governance, controls, and tracking, while also providing for a
higher degree of
authenticity assurance. Additional interfaces (such as the packaging tool noted
earlier) and processes for receiving assets into the archives from external legal
enterprises, e.g., separate agencies and businesses also may be provided. It will
be appreciated that certain example embodiments extend the meaning of provenance
to include not only the origin of the records and/or data files and their custodial
history, but also the history of all actions taken on those records and/or data
files within the records archives system. This may provide additional flexibility
as policies on how to establish authenticity change over time by providing additional
information that can be exploited by such policies.
While the invention has been described in connection with
what are presently considered to be the most practical and preferred embodiments,
it is to be understood that the invention is not to be limited to the disclosed
embodiments, but on the contrary, is intended to cover various modifications and
equivalent arrangements included within the spirit and scope of the invention. Also,
the various embodiments described above may be implemented in conjunction with other
embodiments, e.g., aspects of one embodiment may be combined with aspects of another
embodiment to realize yet other embodiments.
