2. PRESERVATION METADATA: IMPLEMENTATION STRATEGIES The Mission Build on the first OCLC/RLG Working Group and A Metadata Framework to Support the Preservation of Digital Objects Define an implementable set of core preservation metadata elements

3. PRESERVATION METADATA: IMPLEMENTATION STRATEGIES OAIS Information Model Content Information Preservation Descriptive Information Content data object Representation Information Context Info Reference Info Provenance Info Fixity Info

4. PRESERVATION METADATA: IMPLEMENTATION STRATEGIES What is Implementable? 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

5. PRESERVATION METADATA: IMPLEMENTATION STRATEGIES What is Core? What most working preservation repositories are likely to need to know in order to support the long-term Viability, Renderability, Understandability, Authenticity and Identity of archived objects. (Maybe.)

15. PRESERVATION METADATA: IMPLEMENTATION STRATEGIES Format What types of objects have format? Is there a usable authority list of formats? Is there a difference between a format and a profile? Whats a format anyway? What if there are format registries?

26. PRESERVATION METADATA: IMPLEMENTATION STRATEGIES Metadata Best Practices Have a rigorous data model and relate metadata clearly to appropriate objects Store metadata in database and also with content data object Use METS, Z39.87 Store complete metadata for all versions of objects
