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).
