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).
