n.a preservation repository that can prove its reliability over timeRLG 2002, 5A trusted digital repository is one whose mission is to provide reliable, long-term access to managed digital resources to its designated community, now and in the future. In this report the working group has articulated a framework of attributes and responsibilities for trusted, reliable, sustainable digital repositories capable of handling the range of materials held by large and small research institutions. The framework is broad enough to accommodate different situations, architectures, and institutional responsibilities while providing a basis for the expectations of a trusted repository. The critical component will be the ability to prove reliability and trustworthiness over time.Ng, Rubin, and Van Malssen 2010, 20Throughout this report, we argue that sustainable preservation of digital public television content will ideally be achieved by a reliable and responsible entity, or network of entities, which we refer to as a preservation repository. Moreover, successful preservation of digital public broadcast content will only be sustainable if this repository is considered trustworthy, in that it can ensure the long-term accessibility of the digital objects it is storing. To be trustworthy, a repository must: Have a secure technological infrastructure to protect the content; Follow good management procedures that incorporate standards and policies; Have sound organization and governance.Corrado and Moulaison Sandy 2017, 159A trusted digital repository that has a mission to provide long-term access and preservation should expect to perform constant monitoring and be perpetually engaged in planning. In order for a digital preservation system to remain trustworthy, a regular cycle of audit and certification is recommended.
