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);

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
   statement  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
   supporting  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).
