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).
