Hello Bob,
I think I didn't explained well. I didn't mean the ontology file is totally
useless in general, for example it could be very useful when dumping the data
and distribute the full owl with D2RQ.
I meant that it is useless within D2R Server, because it ignores it (AFAIK you
can't get it to be an argument). Of course you can do a lot of things with the
the ontology and D2RQ, but you have to code them manually. Topbraid has coded
some things for you, and for example you can get the ontology and its instances
via D2RQ. All you have to do is defining an ontology and a mapping. I'm asking
if something similar is possible with D2R Server.
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?
Thank you very much again!jfcg
