But at http://dbpedia.org/ontology/ itself I get

<http://dbpedia.org/ontology/> rdf:type owl:Ontology ;
owl:versionInfo "Version 3.5"@en .
Missing a triple such as
<http://dbpedia.org/ontology/> rdfs:isDefinedBy foo
I've got at least a version number :)
So where is the RDF file containing the whole ontology?
[1] references [2], which is a zipped file of the DBPedia Ontology.
However, you are absolutely right, re. Linked Data publishing
principles it might beneficial if, e.g.,
curl -H "Accept: application/rdf+xml" http://dbpedia.org/ontology/
or
curl -H "Accept: application/rdf+xml" http://dbpedia.org/ontology/Person
would resolve to a RDF/XML serialized description. It is a basic
requirement especially re. Semantic Web ontology deployment to serve
semantic graphs in different serializations formats. You are also
right re. the application of rdfs:isDefinedBy for universals that are
part of this ontology.
Cheers,
Bob
