T9 - Towards an International Standard for Audit and Certification of Digital Repositories

David Giaretta, Rutherford Appleton Laboratory

Topic: This presentation will provide an update of the process which aims at developing an ISO standard on which a full audit and certification of digital repositories can be based.

Abstract: Certification of the ability of digital repositories to preserve digitally encoded information over the long-term has been sought for more than a decade. The OAIS Reference Model ( section 1.5: ROAD MAP FOR DEVELOPMENT OF RELATED STANDARDS ) included an item .standard(s) for accreditation of archives., reflecting the long-standing demand for a standard against which Repositories of digital information may be audited and on which an international accreditation and certification process may be based. It was agreed that RLG and NARA take a lead on this follow-on standard. This they did, forming a closed panel. The final version of the RLG/NARA work has been released as .Trustworthy Repositories Audit & Certification: Criteria and Checklist (TRAC). available from This document covers much ground and yet there is still a significant amount of work to be done. Other documents have been produced in this area, including the NESTOR .Catalogue of Criteria for Trusted Digital Long-term Repostories. which is available from The latest step in this process has been the creation of a .Birds of a Feather (BoF). group within the Consultative Committee for Space Data Systems (CCSDS), which aims, as was done with the OAIS Reference Model, at setting up an open international workshops to debate and edit the document which will be submitted via CCSDS into ISO, with full open international review. The significant point is the openness of the process under which this work is being undertaken - see This presentation will provide details of the activities so far, describe the challenges which lie ahead, and discuss the potential significance of this effort.
