This is a patent application. The patent has not been granted yet. Regardless of what we feel are the chances for its success we should argue against it because, if it is granted, all vendors may end up paying Microsoft to license the technology. What we need are publicly available papers that describe SPARQL to SQL mapping. In the reference from Ivan Herman Jim Hendler says they did some work in this area. Perhaps Virtuoso has something in its product literature that we can cite. There may be other papers that RDB2RDF WG members have published. The technique seems to depend on a particular method for storing the triples. I could not figure this out as I did not get the figures with the application. If, of course, the technique works only with a special storage strategy then it does not apply if you store the triples in a different way.
