  1. Metadata for Digital Preservation: A Status Report on PREMIS Priscilla Caplan, FCLA Nancy Hoebelheinrich, Stanford University CNI Fall Task Force Meeting December 6-7, 2004

  2. OCLC/RLG Preservation Metadata Framework Working Group • OCLC/RLG Preservation Metadata Working Group • Convened March 2000 • Looked at CEDARS, NLA, NEDLIB, OCLC • Preservation metadata framework (June 2002) • Synthesized elements from existing sets • Based on OAIS information model • Set of “prototype” preservation metadata elements CNI Fall 2004 Metadata for Digital Presrvation

  3. PREMIS • June 2003: OCLC/RLG sponsored new working group: PREMIS • Preservation Metadata: Implementation Strategies • Objectives • Define “core” set of preservation metadata elements, with supporting data dictionary, applicable to broad range of digital preservation activities • Identify and evaluate alternative strategies for encoding, storing, managing, and exchanging preservation metadata • http://www.oclc.org/research/projects/pmwg/ CNI Fall 2004 Metadata for Digital Presrvation

  6. Implementation Survey Report • State of the art in Winter, 2003/2004 • 28 libraries, 7 archives, 3 museums, and 11 other • 13 different countries; 45% from U.S. • 38% in planning; 33% development; 46% production CNI Fall 2004 Metadata for Digital Presrvation

  7. Core Elements • Mission: Define a core set of implementable preservation metadata elements. CNI Fall 2004 Metadata for Digital Presrvation

  8. Core Elements • Mission: Define a core set of implementable preservation metadata elements. • Information that supports and documents the digital preservation process; • Information that supports the the viability, renderability, understandability, identity and authenticity of digital objects over time. CNI Fall 2004 Metadata for Digital Presrvation

  9. Core Elements • Mission: Define a core set of implementable preservation metadata elements. • What most working preservation repositories are likely to need to know. CNI Fall 2004 Metadata for Digital Presrvation

  10. Core Elements • Mission: Define a core set of implementable preservation metadata elements. • As rigorous as possible • As much explanation as possible • Implementation neutral -- “This is what you have to know” • Values can be automatically supplied and processed -- no lengthy textual descriptions CNI Fall 2004 Metadata for Digital Presrvation

  11. Core Elements: Data Model CNI Fall 2004 Metadata for Digital Presrvation

  17. Semantic units pertaining to Rights • permissionStatement • relatedObject • grantingAgent • grantingAgreement • permission • act • restriction CNI Fall 2004 Metadata for Digital Presrvation

  18. Next steps: PREMIS ACTIVITIES • Complete data dictionary (January 2005) • Write narrative report • Develop XML schemas for exchanging metadata FOLLOW-UP ACTIVITIES • Community outreach • Establish feedback/maintenance mechanism • Testbeds for implementation and exchange CNI Fall 2004 Metadata for Digital Presrvation
