Dear all,

In my local ontology I am trying to add some external resource from DBpedia and Freebase to link them to same individuals (with owl:sameAs property). I also insert some Wikipedia pages and related property foaf:isPrimaryTopicOf.

While in the second case they are accepted as individuals of the class owl:externalresource, in the first they appear under owl:Thing with a globe near. Do you know why?

are http://dbpedia.org/resource/... the correct form for referring to a DBpedia resource?: I mean if I want to say that an individual of my ontology is protege:sameAs an individual of DBpedia have I to use the URL form -http://dbpedia.org/resource/...- to refer to the DBpedia resource? I'm using Protege 3.4.6, and I insert external resource as individual of the protege:externalresource (do you know why the circle near it is shaded?).

thank you all

For this part of the question, I've never heard of the class owl:externalresource. What does "they" refer to here? Can you edit your question to clarify? Where does this class name come from?

might mean protege:ExternalResource ?

what version of protege are you using (Help-About: Version and Build)?

Also how are you adding external resources?

for the second part of the question - be careful about the www subdomain ie. it should be "http://dbpedia.org/resource/Berlin" rather than "http://www.dbpedia.org/resource/Berlin". (also note the "http://")

but you are right in that it should be /resource/ and not be /page/ or /data/
