PREMIS in TIPR

“Interchange You Can Believe In”


  • 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


Heterogeneous partners
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


Key decisions
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


Rxp structure

Progress to date
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


Inter repository service agreement
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
