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

Preservation Metadata: Implementation Strategies CNI Fall 2004 Metadata for Digital Presrvation 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

Preservation Metadata: Implementation Strategies CNI Fall 2004 Metadata for Digital Presrvation 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 

Preservation Metadata: Implementation Strategies CNI Fall 2004 Metadata for Digital Presrvation Core Elements  Mission: Define a core set of implementable preservation metadata elements.

Preservation Metadata: Implementation Strategies CNI Fall 2004 Metadata for Digital Presrvation 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.

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

Preservation Metadata: Implementation Strategies CNI Fall 2004 Metadata for Digital Presrvation 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
