NAME
       libraptor2 - Raptor RDF syntax library 2.0

SYNOPSIS
       #include	<raptor2.h>

       world=raptor_new_world();
       raptor_parser *p=raptor_new_parser(world,rdfxml);
       raptor_set_statement_handler(p,NULL,print_triples);
       raptor_uri *file_uri=raptor_new_uri(world,http://example.org/);
       raptor_parser_parse_file(p,file_uri,base_uri);
       raptor_parser_parse_uri(p,uri,NULL);
       raptor_free_parser(p);
       raptor_free_uri(file_uri);
       raptor_free_world(world);

       cc prog.c -o prog `pkg-config raptor2 --cflags` `pkg-config raptor2 --libs`

DESCRIPTION
       The  Raptor library provides a high-level interface to a	set of parsers
       and serializers that  generate  Resource	 Description  Framework	 (RDF)
       triples by parsing syntaxes or serialize	the triples into syntaxes.

       The  supported  parsing	syntaxes  include  RDF/XML, N-Triples, Turtle,
       TRiG, RSS tag soup (including all RSS and Atoms), GRDDL,	RDF/JSON, RDFa
       and the serializing syntaxes include RDF/XML (3 varieties), N-Quads, N-
       Triples,	Turtle,	RSS 1.0, Atom 1.0, GraphViz  DOT  and  RDF/JSON.   The
       RDF/XML parser can use either expat or libxml XML parsers for providing
       the SAX event stream.  The library functions are	arranged in an object-
       oriented	 style	with  constructors, destructors	and method calls.  The
       statements and error messages are delivered via callback	functions.

       Raptor also contains classes to support the RDF graph triples: a	state-
       ment  object containing term objects and	support	for RDF	URI-References
       for both	parsing	them and resolving / retrieval of URIs.

       It some utility classes such as an I/O Stream abstraction for  support-
       ing  reading and	writing	to and from a variety of locations, AVL	Trees,
       String buffers and Sequences.

       Raptor uses Unicode strings for RDF literals  and  URIs	and  preserves
       them  throughout	the library.  It uses the UTF-8	encoding of Unicode at
       the API for passing in or returning Unicode strings.   It  is  intended
       that  the  preservation	of Unicode for URIs supports Internationalized
       Resource	Identifiers (IRIs).
