Request for RDB2RDF mappings

Hi all,

I am working with RDB2RDF mappings, I am studying the way these mappings,
usually providing instances, relate with the ontologies (T-Box) and thus
with the classes for these instances. Specially, the coverage that mappings
provide to the ontology wrt instances and the inference that the ontology
adds to the underlying RDB. I am requesting your help to increase my
collection of mappings and ontologies to a representative sample of the
state of the art and current status of mappings and mapped ontologies (when
using specific ontologies). All mapping files and ontologies either attached
or linked by mail are greatly welcome.

Thank you very much in advance,

    Jose Mora.
