3. 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
4. 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
5. 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
6. 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
