We have released an update of Virtuoso Open Source Edition and the OpenLink Data Spaces suite.

This marks the coming of age of our RDF and SPARQL efforts. We have the new SQL cost model with SPARQL awareness, we have applications which present much of their data as SIOC, FOAF, ATOM OWL and other formats.

We continue refining these technologies. Our next roadmap item is mapping relational data into RDF and offering SPARQL access to relational data without data duplication. Expect a white paper about this soon.
