       raptor_parser_parse_file(p,file_uri,base_uri);

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).
