Trustworthy Repositories Audit & Certification (TRAC) is a document describing the metrics of an OAIS-compliant digital repository that developed from work done by the OCLC/RLG Programs and National Archives and Records Administration (NARA) task force initiative. The TRAC checklist is an Auditing tool to assess the reliability, commitment and readiness of institutions to assume long-term preservation responsibilities. Currently the repository is under the care of the CRL who are utilizing it in several independent projects. The TRAC checklist was superseded in 2012 by the ISO 16363, known as the Trusted Digital Repository (TDR) Checklist. ==History== In 1996 the Consultative Committee for Space Data Systems established a task force that developed OAIS, a high-level model for the operation of archives. OAIS was accepted as ISO 14721 in 2002. The original task force stated that an independent auditing method was necessary to certify OAIS-compliance and thus engender trust. However, despite the lack of certified auditors and auditing metrics, repositories were already implementing OAIS concepts and labeling themselves OAIS-compliant.〔(【引用サイトリンク】 title=NARAtions )〕 Development of OAIS auditing metrics began in 2003. A joint task force of OCLC/RLG and NARA built upon a previous OCLC/RLG project, Trusted Digital Repositories: Attributes and Responsibilities,〔(【引用サイトリンク】 title=Trusted Digital Repositories: Attributes and Responsibilities )〕 and wrote the metrics collectively known as Trustworthy Repositories Audit & Certification (TRAC). After the publication of TRAC in 2007, CRL was given the responsibility to carry out test audits using the metrics. TRAC is the basis of the Trusted Digital Repository (TDR) document that was accepted as ISO 16363 in 2012.〔(【引用サイトリンク】 title=September 2011 Magenta Draft of ISO 16363 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Trustworthy Repositories Audit & Certification」の詳細全文を読む スポンサード リンク
