Raptor RDF Parser Toolkit

OVERVIEW

Raptor is the RDF Parser Toolkit for Redland and currently consists of two parsers: RDF/XML and N-Triples. Raptor is designed to integrate closely with Redland and also work entirely standalone, in which case it will use simple internal routines to perform the functions.

This library is Beta quality - most things work now. See the todo list for more information. Changes can be found in the NEWS file or more detailed changes in the ChangeLog.

RAPTOR RDF/XML PARSER

• An RDF/XML Parser written in C designed to integrate well with Redland
• Can extract RDF content embedded in XML (such as XHTML)
• Handles rdf:resource / resource attributes
• Optionally can interpret container elements (only) as typedNode after the proposed interpretation by Brian McBride and myself.
• Parsing tracks the formal grammar productions closely - this can be followed when debugging.
• Uses expat and/or (GNOME) libxml XML parsers as available or required
• Has hooks for new parseType-s and container types
• Provides features to select options at run time.
• (Perl and Python interfaces when used via Redland)
• No memory leaks
• Fast

This is beta quality software - the APIs may change, it is mostly feature complete but needs more testing for conformance.

RAPTOR NTRIPLES PARSER

A parser for the N-Triples format which emits RDF statements and is used by the RDF Core working group for test cases.

DOCUMENTATION

There is no documentation at present, only the rdfdump.c example program source to see how to call the parser.
