They are a sequence of three raptor_identifier which cover the RDF terms of URI (RAPTOR_IDENTIFIER_TYPE_RESOURCE), Literal (RAPTOR_IDENTIFIER_TYPE_LITERAL) and Blank Node (RAPTOR_IDENTIFIER_TYPE_ANONYMOUS). Some other raptor_identifer_type forms exist but are deprecated. raptor_genid_typetypedef enum { RAPTOR_GENID_TYPE_BNODEID, RAPTOR_GENID_TYPE_BAGID } raptor_genid_type; Intended type for a generated identifier asked for by the handler registered with raptor_set_generate_id_handler().

Constructs a new identifier copying the URI, ID fields. SHARED means raptor_new_identifier owns this argument after calling. type : raptor_identifier_type of identifier uri : raptor_uri of identifier (if relevant) (SHARED) uri_source : raptor_uri_source of URI (if relevant) id : string for ID or genid (if relevant) (SHARED) literal : string for literal (SHARED) literal_datatype : raptor_uri of identifier (SHARED) literal_language : literal language (SHARED) Returns : a new raptor_identifier object or NULL on failure raptor_copy_identifierint raptor_copy_identifier (raptor_identifier *dest, raptor_identifier *src); Copy raptor_identifiers. dest : destination raptor_identifier (previously created) src : source raptor_identifier Returns : Non 0 on failure raptor_free_identifiervoid raptor_free_identifier (raptor_identifier *identifier); Destructor - destroy a raptor_identifier object. identifier : raptor_identifier object raptor_statementtypedef struct { const void *subject; raptor_identifier_type subject_type; const void *predicate; raptor_identifier_type predicate_type; const void *object; raptor_identifier_type object_type; raptor_uri *object_literal_datatype; const unsigned char *object_literal_language; } raptor_statement; An RDF triple See raptor_identifier for a description of how the fields may be used.

Resource and datatype URIs are compared with raptor_uri_compare(), blank nodes and literals with strcmp(). If one literal has no language, it is earlier than one with a language. If one literal has no datatype, it is earlier than one with a datatype. s1 : first statement s2 : second statement Returns : <0 if s1 is before s2, 0 if equal, >0 if s1 is after s2 raptor_print_statementvoid raptor_print_statement (const raptor_statement *statement, FILE *stream); Print a raptor_statement to a stream. statement : raptor_statement object to print stream : FILE* stream raptor_print_statement_as_ntriplesvoid raptor_print_statement_as_ntriples (const raptor_statement *statement, FILE *stream); Print a raptor_statement in N-Triples form. statement : raptor_statement to print stream : FILE* stream raptor_print_statement_detailedvoid raptor_print_statement_detailed (const raptor_statement *statement, int detailed, FILE *stream); raptor_print_statement_detailed is deprecated and should not be used in newly-written code.

Turns the given term into an N-Triples escaped string using all the escapes as defined in http://www.w3.org/TR/rdf-testcases/ntriples The part (subject, predicate, object) of the raptor_statement is typically passed in as term, the part type (subject_type, predicate_type, object_type) is passed in as type. When the part is a literal, the literal_datatype and literal_language fields are set, otherwise NULL (usually object_datatype, object_literal_language). term : raptor_statement part (subject, predicate, object) type : raptor_statement part type literal_datatype : raptor_statement part datatype literal_language : raptor_statement part language len_p : Pointer to location to store length of new string (if not NULL) Returns : the new string or NULL on failure.
