Dave Beckett has released the Raptor RDF Parser Toolkit 1.4.0, an open source C library for parsing the RDF/XML, N-Triples. Turtle, and Atom Resource Description Framework formats. It uses expat or libxml2 as the underlying XML parser. Version 1.40 can serialize RDF triples into RDF/XML and N-Triples and adds RSS enclosure support to the RSS tag soup parser. Raptor is dual licensed under the LGPL and Apache 2.0 licenses.
