There are now a number of libraries for processing some of the technologies upon which RDF/XML is built. Particularly, Closure XML is a robust, mature XML parser, and manipulation of URIs is easy using Puri.
This RDF/XML parser builds upon these libraries so as to minimize the amount of code that is not directly related to parsing RDF/XML, and provides a simple interface for extracting triples from RDF/XML documents.
Documentation generated by documentation-template is available at the project's prior home.
