P1484.12.4 RDF binding PAR (Approved by LOM WG)
  • SCOPE
  • This standard specifies a W3C RDF (Resource
    Description Format) binding of the IEEE 1484.12.1
    data model.
  • An implementation that conforms to 1484.12.4 must
    conform to 1484.12.1.
  • PURPOSE
  • The purpose of this standard is to provide the
    RDF binding to enable the exchange of LOM
    instances between conforming systems that
    implement the 1484.12.1 data model.

Status
  • Drawing from existing work
  • IMSwww.imsglobal.org/rdf (initiated in March
    2001)
  • Mikael Nilssons draftskmr.nada.kth.se/el/ims/md

    ms/metadata.html(checked with W3C RDF validator)

Issues
  • Technical
  • Semantics!
  • LOM data elements can be represented in many ways
    using RDF richer structures
  • RDF statements
  • RDF for DC, DCQ, LOM (following Ottawa)
  • URIs for all voabularies
  • namespace syntax
  • Mikaels slides
  • Other
  • - scheduling conference calls!

10
Workplan
  • Finalization date not yet determined
  • Work completed
  • - existing relevant work identified- issues
    requiring resolution identified- drafting is
    proceeding
