CEO of MySQL "Invents" the Semantic Web! at MindingThePlanet
"It would be a terrible waste if MySQL went off on their own to reinvent the wheel (a wheel which has taken hundreds of researchers more than a decade to make) when they could be valuable contributors of an already-existing, large-scale, worldwide community that is very far along in making the vision Mr. Mickos described into a reality. MySQL could indeed play THE leading role in this space. They are perfectly positioned to do it."
