When the RDB2RDF WG was working I suggested including an RDB ontology.
But it was considered out of scope so nothing of the sort was included
in their final deliverables.

My work didn't (and doesn't) involve RDBMS deeply enough to pursue this,
so I don't know how valuable this would be for practical tasks.
