.SH DESCRIPTION
The \fIRaptor\fP 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.
.LP
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 \fIexpat\fP or \fIlibxml\fP
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.
.LP
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.
.LP
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.
.LP
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).
