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

Thank you Bernard and Bob for this wonderful exchange !!
FYN is important to both the TBox and ABox. In short, the combination is
lethal when it comes to unveiling the real magical prowess of Linked Data.
We are making a really important turn towards improved clarity and
consistency re. Linked Data theory and actual practice.
Kinda ironic this happens on 1st April. LOL!
