RDF Statement / Assertion / Triple

This module provides the RDF statement functionality, and contains three parts: resource, predicate and object which are all nodes provided by the librdf_node class. Statements can be added / removed from models.

Statements have at least one rdf:type and are always of rdf:type rdf:resource. They can be present in the model and/or reified in which they are quoted or talked about by other statements.
