Trustworthy Repositories Audit and Certification
n. (abbr. TRAC)
a set of criteria used to assess and certify Open Archival Information System–compliant digital repositories
In 2007, the Research Libraries Group–National Archives and Records Administration Digital Repository Certification Task Force established the Trustworthy Repositories Audit and Certification (TRAC): Criteria and Checklist as an audit tool and certification methodology for demonstrating the trustworthiness of digital repositories.
The TRAC checklist provides digital repositories a framework and process to measure, evaluate, and document degrees of compliance with the Open Archival Information System (OAIS) Reference Model.
TRAC metrics also provide the basis for the Trusted Digital Repository (TDR) Checklist, an ISO standard (ISO 16363) for the Audit and Certification of Trustworthy Digital Repositories.
