RDF Triples

CWRC-Writer allows users to markup their document with Triples. In this document we provide and overall description of RDF triples.


When using RDF, the metadata is encoded as a triples. They use Uniform Resource Identifiers (WRI) to identify the relationships between the links (this is the triple).

Components of a RDF Triple:
  • The Objectis the object or value of the RDF annotation.
  • The Subject identifies what the object is describing in the annotation.
  • The Predicate points to the section of data in the object that the RDF annotation is giving a value to.
