Yes. I completely Agree, that would be consistent with the OWL-Way of referring to Data or Object Properties. That would allow to put axioms on the Property Page like "P1 owl:sameAs P2" or whatever. > > 3.)

The full link would then point to the Property page, or to some property of a another Ontology. But in the latter case the predicate-Links cannot be stored as backlinks. I think it should be possible to write a plugin which would also attach/embed the rdf representation of the Links into the retrieved html page, so that it can be used by foreign systems/programs.

Also I think it is good in terms of Experience. nice greetings Jonas _______________________________________________ devs mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/devs
