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