<h2>OVERVIEW</h2>
<p><a href="http://www.redland.opensource.ac.uk/raptor/">Raptor</a>
is the
<b>R</b>DF <b>P</b>arser <b>T</b>oolkit f<b>o</b>r
<a href="http://www.redland.opensource.ac.uk/"><b>R</b>edland</a>
and currently consists of two parsers: RDF/XML and N-Triples.
Raptor is designed to work efficiently when used with Redland
but is entirely separate.
</p>
<p>This library is mature and <b>Beta</b> quality - most things work
but there are known problems. See
the <a href="TODO.html">todo list</a> for more information. Changes
can be found in the <a href="NEWS.html">NEWS</a> file or more
detailed changes in the <a href="ChangeLog">ChangeLog</a>.</p>
<h2>RAPTOR RDF/XML PARSER</h2>
<ul>
<li>An RDF/XML Parser written in C designed to integrate well with <a href="http://www.redland.opensource.ac.uk/">Redland</a></li>
<li>Handles RDF Core WG syntax updates for XML Base, xml:lang, datatyping.</li>
<li>Generates N-Triples supporting XML literals, language tagging and datatypes</li>
<li>Handles rdf:resource / resource attributes</li>
<li>Uses <a href="http://expat.sourceforge.net/">expat</a> and/or (GNOME) <a href="http://xmlsoft.org/">libxml</a> XML parsers as available or required</li>
<li>Provides features to select options at run time.</li>
<li>(Perl, Python, Java, Tcl, Ruby, PHP interfaces when used via Redland)</li>
<li>No memory leaks</li>
<li>Fast</li>
</ul>
<p>This is stable software - the APIs are unlikely to change and it
is nearly feature complete (as an RDF/XML parser).</p>
<h2>RAPTOR NTRIPLES PARSER</h2>
<p>A parser for the
<a href="http://www.w3.org/TR/rdf-testcases/#ntriples">N-Triples</a>
format which emits RDF statements and is used by the RDF Core
working group for test cases.
</p>
<h2>DOCUMENTATION</h2>
<p>The API is described in the <em>libraptor.3</em> UNIX manual page.
It is demonstrated in the <em>rapper.1</em> utility program which
shows how to call the parser and get back the triples. When raptor
is used inside
<a href="http://www.redland.opensource.ac.uk/">Redland</a>,
the Redland documentation explains
how to call the parser and contains several example programs.</p>
<p>To install see the <a href="INSTALL.html">Installation document</a></p>
<h2>TODO / BUGS</h2>
<p>See the <a href="TODO.html">TODO</a> page for the current status.</p>
