Rx4RDF is a specification and reference implementation for querying, transforming and updating W3C's RDF by specifying a deterministic mapping of the RDF model to the XML data model defined by XPath. Rx4RDF shields developers from the complexity of RDF by enabling you to use familar XML technologies like XPath, XSLT and XUpdate. We call their RDF equivalents RxPath, RxSLT, and RxUpdate respectively.
