Description

This module presents RDF concepts from either the RDF namespace http://www.w3.org/1999/02/22-rdf-syntax-ns# or the RDF Schema namespace http://www.w3.org/2000/01/rdf-schema#

This list includes both syntax terms such as rdf:li as well as model concepts (RDF properties or classes) such as rdf:Seq

These are used in code using two lists of macros to get fast pointers to librdf_node or librdf_uri objects for the concept. These should be copied with the appropriate librdf_node or librdf_uri class copy constructors before use.

Example 1. Using macros to get a node and URI for an RDF concept
