The CoreTrustSeal position paper on Curation & Preservation Levels provides the Board, and potential applicants, with a reference point for defining repositories that are in scope for certification. Current CoreTrustSeal Trustworthy Digital Repository (TDR) certification is limited to candidates that take responsibility for active long-term preservation. Active preservation repositories may also intervene in other points in the digital object lifecycle. These intervention points, as defined in the CoreTrustSeal levels of care, include criteria that digital objects must comply with at the point of deposit and after initial curation. All of the levels assume a retention commitment. This discussion paper briefly describes the wider significance of the curation and preservation levels and their alignment with the CoreTrustSeal Requirements. This has implications for the specification of supporting evidence for compliance, including that provided by third party service providers, and potential future assessment and certifications approaches.
