"Raptor is a Open Source C library for parsing RDF syntaxes into RDF triples. It supports the latest revision of RDF/XML (including collections and datatypes), N-Triples, and some XML RSS via a tag soup parser. It handles the RDF/XML used by RDF applications such as RSS 1.0, FOAF, Dublin Core, and OWL. It can use either expat or libxml2 for XML parsing, libcurl when available for URI retrieval, and is portable to many POSIX systems (Unix, GNU/Linux, BSDs, OSX, cygwin, win32).

Raptor [was designed as the parser module of the] Redland RDF Library but is fully separate. Redland is a library that provides a high-level interface for RDF allowing the RDF graph to be parsed from XML, stored, queried and manipulated. Redland implements each of the RDF concepts in its own class via an object based API [and has] Java, Perl, PHP, Python, Ruby and Tcl interfaces for manipulating the RDF graph and parts."
