5 * Hooks provided by the RDF module.
14 * Allow modules to define namespaces for RDF mappings.
16 * Many common namespace prefixes are defined in rdf_rdf_namespaces(). However,
17 * if a module implements rdf mappings that use prefixes that are not
18 * defined in rdf_rdf_namespaces(), this hook should be used to define the new
22 * An associative array of namespaces where the key is the namespace prefix
23 * and the value is the namespace URI.
