I have to agree that almost all the semantic websites I've seen, with huge list of triples, look at best discouraging, at worst impenetrable. But for a core set of lenses you require some standard, no ? Do you have some specific use-cases to begin with ? best, Andrea Il giorno 11/ott/07, alle ore 07:09, Chris Mungall ha scritto: > > > Sorry to repost something from a list many of you are already > subscribed to; however, this seems like it warrants some specific > discussion on this list. > > I know many of you have been wrapping various biological > datasources as RDF - I have been doing the same, using the usual > suspects such as R2RQ and Sesame.
