The Center for Research Libraries and RLG Programs have published the Trustworthy Repositories Audit & Certification: Criteria and Checklist.
Here’s an excerpt from the press release:
In 2003, RLG and the US National Archives and Records Administration created a joint task force to address digital repository certification. The goal of the RLG-NARA Task Force on Digital Repository Certification was to develop criteria to identify digital repositories capable of reliably storing, migrating, and providing access to digital collections. With partial funding from the NARA Electronic Records Archives Program, the international task force produced a set of certification criteria 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. . . . .
In 2005, the Andrew W. Mellon Foundation awarded funding to the Center for Research Libraries to further establish the documentation requirements, delineate a process for certification, and establish appropriate methodologies for determining the soundness and sustainability of digital repositories. Under this effort, Robin Dale (RLG Programs) and Bernard F. Reilly (President, Center for Research Libraries) created an audit methodology based largely on the checklist, tested it on several major digital repositories, including the E-Depot at the Koninklijke Bibliotheek in the Netherlands, the Inter-University Consortium for Political and Social Research, and Portico.
Findings and methodologies were shared with those of related working groups in Europe who applied the draft checklist in their own domains: the Digital Curation Center (U.K.), DigitalPreservationEurope (Continental Europe) and NESTOR (Germany). The report incorporates the sum of knowledge and experience, new ideas, techniques, and tools that resulted from cross-fertilization between the U.S. and European efforts. It also includes a discussion of audit and certification criteria and how they can be considered from an organizational perspective.
