Trustworthy repository criteria, virtual organizations, and infrastructure

Chronopolis is a geographically dispersed preservation system based on the SRB/iRODS platform. It ensures the trustworthiness of digital objects through regular fixity checking and is moving towards using open tools like BagIt. With active collaborations and partnerships, such as MetaArchive, Chronopolis aims for auditable processes and improvements in long-term planning, common language, and technology sharing. This assessment-driven initiative promotes transparency, policy evaluation, and practical collaboration in preserving digital content.

Presentation Transcript

  1. Trustworthy repository criteria, virtual organizations, and infrastructure Chronopolis

  2. Current Chronopolis state • SRB/iRODS based, geographically dispersed preservation system • Perform fixity checking on regular basis for all objects in the system • Moving towards more “open” tools (e.g. BagIt) in defining process • Currently have ~25TB under management

  3. Two big pushes • Auditable processes: full TRAC assessment • Starting … NOW • Partnerships: active collaborations • MetaArchive (several areas) • … others coming

  4. TRAC • Being conducted by CRL • Self assessment being done now • Completed in early 2011 • An opportunity not just for assessment but for development • Improves common language • Helps with long-term planning

  5. Collaborations • MetaArchive • Management discussions • Technology sharing (iRODS and LOCKSS) • Grants and projects • Others coming…

  6. Collaborations … (TRAC fueled) • Help: safety of bits, avoid technology blinders, development and planning, sustainability • Complications: safety of objects (?), data ownership, sustainability

  7. What is Trust? • Transparency – organizationally, grants and planning, collaboration rather than collabetition • Common language on objects and infrastructure

  8. Policy and evaluation • Policies: what parts of the infrastructure affect how bits are treated; what impact do the content contributors have? • Assessment of collaboration should be driven by the practical, not only the theoretical.
