PREMIS in TIPR

TIPR (Transfers of Interchange You Can Believe In) is a partnership between FCLA, Cornell, and NYU, funded by the IMLS. The goal is to demonstrate the feasibility of transferring rich AIPs between repositories, identify challenges, and develop a standards-based transfer format. The project disseminates its results to the preservation community and relevant standards efforts.

  1. PREMIS in TIPR “Interchange You Can Believe In”

  2. TIPR – a partnership between FCLA, Cornell and NYU • Generously funded by the IMLS • Goals: • Demonstrate feasibility of repository-to-repository transfer of rich AIPs • Identify issues that impede such transfers • Develop a usable, standards-based transfer format • Disseminate results to the preservation community and relevant standards efforts

  3. Heterogeneous Partners • FCLA runs DAITSS for the Florida Digital Archive • Cornell University Libraries runs an aDORe-based repository, migrating to Fedora • NYU Libraries runs a DSpace based repository

  4. Key Decisions • Use standards: PREMIS and METS • Follow PREMIS data model for Intellectual Entity, Representations, Files • Support arbitrary number of representations in any AIP • Repositories should understand METS syntax and PREMIS semantics • Digital provenance must be maintained through transfer

  5. RXP Structure Optional OpenPGP signature ./rxp.xml.sig ./rxp.xml Package (RXP) level information ./rxp-digiprov.xml ./rxp-rights.xml ./rxp-rep-1.xml Representation level information, repeated for each representation ./rxp-rep-1-digiprov.xml Directory containing representation files ./files/

  6. Package (RXP) level information METS document describing sender ./rxp.xml PREMIS document with package-level provenance ./rxp-digiprov.xml PREMIS document with package-level rights ./rxp-rights.xml

  7. Representation level information Representation level information is repeated for each representation METS document describing rep- resentation ./rxp-rep-1.xml PREMIS document with representation -level provenance ./rxp-rep-1-digiprov.xml

  8. Progress to Date • Transfer format defined and RXP spec drafted • Schematron validation for RXP, PREMIS, METS • Each partner can produce RXP for sample AIPs • Each partner has ingested RXP from other partners

  9. Inter-Repository Service Agreement • Presented at iPRES 2010 • Make RXF relatively constrained, put flexibility in IRSA • Current standards address Producer to Archive (Repository) • Repository to Repository has additional challenges
