Just to clarify one point, the OAIS actually is an ISO standard--ISO 14721:2003. I only mention it because I believe that one of the most important keys to success for long-term preservation is the pervasive use of standards.

I think your point was that the reference model doesn't specify how to map information into the model. But, it does say what information is required and where to put it in the model. Would you agree with that?

Also, section 3.1 specifies mandatory responsibilities and some of these have an impact on the IT functions of the archive. So, that would be another place where the OAIS has to be treated like a standard, not merely a strong recomendation.

We completely agree with Ken's comments that OASIS is a standard, one which we are indeed following. We are also following DACS (Describing Archives: A Content Standard http://www.archivists.org/governance/standards/dacs.asp) an output-neutral set of rules for describing archives, personal papers, and manuscript collections, and can be applied to all material types. It is the U.S. implementation of international standards (i.e., ISAD(G) and ISAAR(CPF)) for the description of archival materials and their creators.

We are also following Dublin Core (ISO Standard 15836-2003 of February 2003 [ISO15836], ANSI/NISO Standard Z39.85-2007 of May 2007 [NISOZ3985], and IETF RFC 5013 of August 2007 [RFC5013]. The Dublin Core Metadata Element Set is a vocabulary of fifteen properties for use in resource description. The fifteen element "Dublin Core" described in this standard is part of a larger set of metadata vocabularies and technical specifications maintained by the Dublin Core Metadata Initiative (DCMI). The full set of vocabularies, DCMI Metadata Terms [DCMI-TERMS], also includes sets of resource classes (including the DCMI Type Vocabulary [DCMI-TYPE]), vocabulary encoding schemes, and syntax encoding schemes. The terms in DCMI vocabularies are intended to be used in combination with terms from other, compatible vocabularies in the context of application profiles and on the basis of the DCMI Abstract Model [DCAM] http://dublincore.org/documents/dces/.

What we were describing as a reference model was the "Trusted Digital Repositories" document. From the document: "In 2002, RLG and OCLC jointly published "Trusted Digital Repositories: Attributes and Responsibilities" (TDR), which...articulated a framework of attributes and responsibilities for trusted, reliable, sustainable digital repositories capable of handling the range of materials held by large and small cultural heritage and research institutions....In 2003, RLG and the National Archives and Records Administration created a joint task force to specifically address digital repository certification. The goal of this task force 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."

As part of the National Archives and Records Administration, the John F. Kennedy Presidential Library and Museum staff believes we should be adopting the Trusted Digital Repositories report as our guideline. However, we may not be able to adopt every criteria particularly because this document is based upon born digital objects, while we are creating digital surrogates. We are making every effort to adhere to the guidelines in order to meet the certificate criteria to become a Trusted Digital Repository.

Your clarification was indeed on the mark and I updated my post to more accurately reflect both OAIS and TDR. Thanks for the contribution.
