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).
