Hi Juan,t it seems that I probably do not really get what your problem might be (all other reading the mailing, you are invited to help me as well ;) ).

An ontology in general is a separate construct that can be utilised in a D2RQ mapping. For example, when you dump the triples that you will get via your mapping and load them into a proper triple store รก la OpenLink Virtuoso or Ontotext Big OWLIM then you can apply proper inferencing task on these descriptions as well, e.g., deriving sub-class relations. > > I meant that it is useless within D2R Server, because it ignores it > (AFAIK you can't get it to be an argument). Well I probably tried to explain you this already in a previous reply. AFAIK you cannot do any inferencing with D2R (Richard or someone else please correct me here if I'm wrong). > Of course you can do a lot > of things with the the ontology and D2RQ, but you have to code them > manually. If you wanna apply an existing (or separately created) ontology in your mapping then you have to do this task more or less manually, but this is more or less the main work one has to do when applying D2R. > Topbraid has coded some things for you, and for example you > can get the ontology and its instances via D2RQ.

Yes, and I think this is more or less the essence I tried to explain you via my previous e-mails ;) > > So, my question would be if the ontology file is useful with D2R Server > directly (like with Topbraid, for example)? Or you have to use D2RQ > Engine to publish your full ontology info in the web? Usually you would publish your ontology specification separately (see [1]).
