Thanks for the follow up! I find very interesting the response of Dr. Atkinson. I am very happy to hear that the OGSA-DAI project is open to suggestions and collaborations. Personally I think the integration of the semantic web technologies is very important and the OGSA-DAI project members should think very seriously of pursuing this direction. In my view if each data source is described by some ontology, the data are presented using RDF, and SPARQL is used as a query language then the transparent integration of any data source (of unknown nature, be it XML or relational) will become a reality.

I would be more than delighted to see the whole Globus Toolkit become more conformant to the semantic web. In some ways I agree with Mark Baker that you the Grid guys have embraced Web Services but have more or less put aside the Web and I think the Grid community and the tool developers in particular should try to collaborate more closely with the (semantic) Web guys to implement the vision of the Semantic Grid..

Best regards,
P.S. BTW my last name is "Sfakianakis" not "Stafianakis" :-D
