Metadata Element Set Registry: Enhancing Semantic Structure

The Metadata Element Set Registry by UKOLN offers a platform to discover, compare, and align metadata schemas for human readers and software agents. Explore namespaces, elements, and schemes for validation and mapping. Join to refine semantics and facilitate machine-readability.

  1. Registry of MEG-related schemas Email p.johnston@ukoln.ac.uk URL http://www.ukoln.ac.uk/ Pete Johnston UKOLN University of Bath Bath, BA2 7AY UKOLN is supported by:

  2. Purpose • Make structure/semantics of metadata element sets available to • human reader • discover what is available • explore, compare existing entries • bring own work into alignment • software agent • need schemas to interpret instances • validation • mapping

  3. DESIRE registry • Model • Namespaces, elements, schemes • Application profiles • select elements • constrain values • constrain obligation/occurrence • refine semantics • For human reader

  4. Namespaces DC 1.1 DCQ 2000-07-11 DC-ED IEEE LOM, WD 4.0 IMS Learning Resource Metadata, v1.1 Virtual Teacher Centre, v0.5 Application Profiles DC ED NGfL Scotland EASEL DCMES, Draft IMS LRM Core, v1.1 ADL SCORM, v1.1 MEG-related entries

  5. Issues • Version control/status • reference to source specification • status • date of last modification • “Inheritance” • schemes specified in profile v schemes specified in (namespace) element definition • Extending semantic layer

  6. Future? • More entries please! • Mapping via semantic layer? • Machine-readability • SCHEMAS project • RDF/XML schemas • conventions for describing profiles • registry as “middleware” • version control • support for validation • support for reuse/extensibility
