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
“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”?
OAIS
model implementation
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
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)

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)

with the responsibility of making information available for the Long Term. (1.2)

TRAC
Trustworthy Repositories Audit & Certification Criteria and Checklist
In 2003, RLG and the National Archives and Records Administrationcreated a joint task force to specifically address digital repositorycertification. The goal of the RLG-NARA Task Force on DigitalRepository Certification has been to develop criteria to identifydigital repositories capable of reliably storing, migrating, andproviding access to digital collections. The challenge has been toproduce certification criteria and delineate a process forcertification applicable to a range of digital repositories andarchives, from academic institutional preservation repositories tolarge data archives and from national libraries to third-party digitalarchiving services.
TRAC
TRAC is a checklist based on OAIS criteria. TRAC provides a mechanism for measuring
compliance of an archive with OAIS.
