These should be copied with the appropriate librdf_node or librdf_uri class copy constructors before use. #include <redland.h> ... librdf_node* n=librdf_new_node_from_node(LIBRDF_MS_value); librdf_uri* u=librdf_new_uri_from_uri(LIBRDF_MS_value_URI); librdf_get_concept_resource_by_indexlibrdf_node* librdf_get_concept_resource_by_index (librdf_world *world, librdf_concepts_index idx); Get Redland node object for RDF concepts. world : redland world object idx : librdf_concepts_index Returns : librdf_node pointer or NULL on failure. librdf_get_concept_uri_by_indexlibrdf_uri* librdf_get_concept_uri_by_index (librdf_world *world, librdf_concepts_index idx); Get Redland uri object for RDF concepts. world : redland world object idx : librdf_concepts_index Returns : librdf_uri pointer or NULL on failure. librdf_get_concept_ms_namespacelibrdf_uri* librdf_get_concept_ms_namespace (librdf_world *world); Get a shared librdf_uri for the RDF Syntax namespace. world : librdf world object Returns : librdf_uri pointer or NULL on failure. librdf_get_concept_schema_namespacelibrdf_uri* librdf_get_concept_schema_namespace (librdf_world *world); Get a shared librdf_uri for the RDF Schema namespace. world : librdf world object Returns : librdf_uri pointer or NULL on failure.
