OAIS OAIS “The term ‘Open’ in OAIS is used to imply that this Recommendation, as well as future related Recommendations and standards, are developed in open forums, and it does not imply that access to the archive is unrestricted.”
OAIS OAIS “An OAIS is an archive, consisting of an organization of people and systems, that has accepted the responsibility to preserve information and make it available for a Designated Community.
OAIS What is a “Reference Model”? • Not an implementation • Provide framework • Provide concepts • Provide terminology • Provide a foundation
OAIS What is a “Reference Model”? model implementation
OAIS What is a “Reference Model”? • It does not prescribe how to build an archive. • It gives you the terminology to describe what you do and how you do it. • It defines “responsibilities.”
OAIS What is a “Reference Model”? • It does not make decisions for you.
OAIS What is a “Reference Model”? • It helps you identify the decisions you must make. • It helps you choose wisely among alternatives. • It helps you define what you do.
OAIS How to use OAIS • For planning, review, and evaluation • For communication
OAIS How to use OAIS • For communication • With producers • Within your own organization • Colleagues • Management • With other archives and partners • With users
OAIS Simplicity
OAIS Generalizable • Although it focuses on the digital, it is applicable to any archive: • “The information may, in general, be submitted using a wide variety of common and not-so-common forms, such as books, documents, maps, data sets, and moon rocks using a variety of communication paths including networks, mail, and special delivery.” (3.2.1)
OAIS Generalizable • The model is even applicable to facilities that hold information temporarily. (1.2) • The information being maintained has been deemed to need Long Term Preservation, even if the OAIS itself is not permanent. (1.1)
OAIS Generalizable • Applicable both to archives that have steady input streams and to those that have “aperiodic” inputs. • It includes archives that provide a wide variety of sophisticated access services as well as those that support only the simplest types of requests. (2)
OAIS Who has used OAIS? • NEDLIB, DSEP (Deposit System for Electronic Publications) • British Library, Digital Storage Project • Library of Congress • National Archives • Harvard University • Stanford University • RLG and OCLC • National Library of Australia, Pandora Archive • Royal Library of the Netherlands • UK Data Archive (UKDA) at the University of Essex • ICPSR

OAIS Generalizable • …to systems where the Producer role and the archive role are the responsibility of the same entity. • Notes that producer/archivists must realize that “Long Term Preservation activities may conflict with the goals of rapid production and dissemination of products to Consumers.” (2)
OAIS Long Term • “Indefinitely” • “Permanently”
OAIS Long Term • It is specifically applicable to organizations with the responsibility of making information available for the Long Term. (1.2) • And… Not just ‘bit storage’ -- but long-term information preservation and access. (2)
OAIS Conforming to OAIS 3.1 MANDATORY RESPONSIBILITIES • Obtain sufficient control of the information provided to the level needed to ensure Long-Term Preservation. • physical ownership or possession of Content Information • ownership of intellectual property rights in this information
OAIS and Trusted Repositories Trustworthy Repositories Audit & Certification Criteria and Checklist
TRAC In 2003, RLG and the National Archives and Records Administration created a joint task force to specifically address digital repository certification. The goal of the RLG-NARA Task Force on Digital Repository Certification has been to develop criteria to identify digital repositories capable of reliably storing, migrating, and providing access to digital collections. The challenge has been to produce certification criteria and delineate a process for certification applicable to a range of digital repositories and archives, from academic institutional preservation repositories to large data archives and from national libraries to third-party digital archiving services. Trustworthy Repositories Audit & Certification Criteria and Checklist
TRAC • TRAC is a checklist based on OAIS criteria. • TRAC provides a mechanism for measuring compliance of an archive with OAIS. “Stewardship is easy and inexpensive to claim; it is expensive and difficult to honor, and perhaps it will prove to be all too easy to later abdicate” Lynch, Clifford A. February 2003. “Institutional Repositories: Essential Infrastructure for Scholarship in the Digital Age.” ARL BiMonthly Report 226.
