Introduction to Metadata Standards Introduction to Metadata Standards Presentation Transcript

  • Dr David Massart, EUN
    AgLRs – Budapest, Hungary
    Nov. 2, 2009
    A Brief Introduction to Metadata Specifications
  • Learning Objects, Metadata, and Repositories
  • Metadata = Data about Data
    In our context,
    metadata = machine-readable description of learning objects
    Initially used with digital libraries (catalogue of digital resources)
    Create indexes (catalogue search)
    Evaluate search results
  • Metadata Standards
    Avoid reinventing the wheel
    Interoperability (making digital resources globally discoverable)
    Metadata standards and specifications
    Dublin Core
    IEEE Learning Object Metadata
    ISO/IEC SC36/WG4
  • Metadata Standards
    Information model (semantic interoperability)
    Concepts and scope
    Relationships
    Controlled vocabularies
    Bindings (technical interoperability)
    How to represent (encode) a description with a given technology
    Example: The IEEE LOM information model and its XML binding
  • Metadata Standards
    Are (too) generic
    Tend to cover all possible cases
    Are often incomplete
    Need to be profiled (i.e., customized) to the needs of a given community
    Like a metadata standard, a metadata application profile consists of
    A information model and
    One or more bindings
