XRP (a.k.a. the XR platform) is a data management platform for RDF-annotated XML data,
relying on the XR data model and the XRQ query language. The platform works as a data
integrator on top of XML and RDF data management systems. It features components for
query evaluation, optimization and composition, as well as modules for managing XML
node URIs. The platform can be accessed from command-line or through a web-based
interface in the spirit of SPARQL endpoints.
