24 The Raptor library provides a high-level interface to a set of parsers
25 and serializers that generate Resource Description Framework (RDF)
26 triples by parsing syntaxes or serialize the triples into syntaxes.
27 The supported parsing syntaxes include RDF/XML, N-Triples, Turtle,
29 TRiG, RSS tag soup (including all RSS and Atoms), GRDDL, RDF/JSON, RDFa
30 and the serializing syntaxes include RDF/XML (3 varieties), N-Quads, N-
31 Triples, Turtle, RSS 1.0, Atom 1.0, GraphViz DOT and RDF/JSON. The
32 RDF/XML parser can use either expat or libxml XML parsers for providing
33 the SAX event stream. The library functions are arranged in an object-
34 oriented style with constructors, destructors and method calls. The
35 statements and error messages are delivered via callback functions.
36 Raptor also contains classes to support the RDF graph triples: a state‐
38 ment object containing term objects and support for RDF URI-References
39 for both parsing them and resolving / retrieval of URIs.
40 It some utility classes such as an I/O Stream abstraction for support‐
42 ing reading and writing to and from a variety of locations, AVL Trees,
43 String buffers and Sequences.
44 Raptor uses Unicode strings for RDF literals and URIs and preserves
46 them throughout the library. It uses the UTF-8 encoding of Unicode at
47 the API for passing in or returning Unicode strings. It is intended
48 that the preservation of Unicode for URIs supports Internationalized
49 Resource Identifiers (IRIs).
