Also note there is portal re. this information i.e., generating an 
Ontology from a Relational Schema.

Links:

1. http://esw.w3.org/topic/Rdb2RdfXG/StateOfTheArt
2. http://delicious.com/kidehen/rdb2rdf - my collection of links that 
include Virtuoso RDB2RDF functionality (note: this includes a Wizard for 
generating an Ontology and instance data for said ontology from ODBC or 
JDBC accessible Relational Schemas).
