  • Overview Metadata Community Practice Directions
  • Metadata
  • Metadata? Schematized … … statements about … … resources
  • Metadata supports operations on resources …. … and relieves the user of having to have advance knowledge of the characteristics or existence of the resource.
      • Know what resources are available
      • Know how to play a resource
      • Know provenance of a resource
      • Know what use policy governs a resource
      • Know how to ingest a resource
      • Know how to interact with a resource
      • Know how to compose/decompose resources
  • Metadata? … allows people and machines to work smarter …

    • Multiple types of information Objects
    • Collections
    • Services
    • People
    • Organizations
    • Places
    • Terms
    • Formats
    • Rights
    • … and will support multiple operations

      • Requirements
      • Traditions
      • Legacies

    Ontology recapitulates ideology
  • Practice
  • Simple descriptive metadata!! FRBR INDECS CIDOC … MARC21 DC VRA Core MODS Onix … Cataloging rules Controlled vocabs. … XML ISO2709 … RDF ‘ Element set’ Information model Encoding Values/content Application profile
  • Interoperability a factor at all these levels .. For example ..
    • Encoding
    • Element set
    • Content/values
    • Encoding
    • Element set
    • Content/values
  • This gives a context for discussing …
    • Traditional library practice
      • Strive for consistency at all three levels in the ISO 2709/MARC/AACR model
      • Institutionalised in standards, OCLC/RLG/LC, committees, …
    • Dublin Core
      • Consistency of element set
      • A small number of encodings
      • Content/values subject to separate agreement
    • OAI
      • A transport for resources.
      • No control over the transported resources
      • So …
  • The interoperable core and communities of practice? MARC XML MARC 21 ONIX Dublin Core MODS Dublin Core GEM SCORM DC-Ed LOM Godby, Smith and Childress

    • Pressures:
      • Manage in a world of resource abundance
      • Demonstrate value
    • Issues
      • Programmatically promote metadata from resources where possible

      • Increasingly complex relationships between resources
      • Bringing together metadata from different policy regimes
    Fragmentation of community agreements and standards activities?
  • Statements

  • Metadata
    • Schematized statements about resources
    • Historically independent communities of interest overlapping in a network space
    • Practitioners faced with high acronymic density, many choices, and often a moving target
    • Kaleidoscopic perspective .. May fall into pattern at any minute …
  • Over to you … Thank you! Lorcan Dempsey [email_address]
