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.
