Clearly there is growing interest in the Semantic web and associated tools (RDF, N3, OWL, SPARQL etc) and sure enough, we have to believe that if Oracle Corp is spending the money to provide RDF support tools (includibng an Oracle flavored "triple Store"), they must sense that there is a market out there.

I take it that your approach is to keep the legacy RDBMS schema but somehow create a layer over it that can be queried (using SPARQL ? Mixing SPARQL with "normal" Where's and Joins? ) as if the underlying data were actually in Triple form?

I've been poking around the web, and see plenty of companies that say they have something or other involving the "Semantic Web", but very often I cant tell exactly what it is that they are doing, or what problem they are solving, except that they assure me its "Way cool".

I'ld be interested in knowing about various concrete real world problems people are actually having some success with, using semantic web tools or ideas. Received on Mon Dec 03 2007 - 02:06:15 CET
