Dave Beckett, creator of the Redland RDF application framework, has released his RDF parser Raptor as a stand-alone library.

The impressive feature list provided by Beckett includes:

• C-based
• Can extract RDF content embedded in XML (such as XHTML)
• Parsing tracks the formal grammar productions closely
• Uses expat and/or libxml XML parsers as available or required
• Has hooks for new parseType-s and container types
• Perl and Python interfaces, when used via Redland
• No memory leaks
• Fast

Raptor is available either as source or as an RPM for Redhat Linux 6.2. Beckett warns that Raptor is still "alpha quality," and subject to change. Beckett uses the Redland mailing list to provide more information about Rapier updates.
