Hi all,

how come the OWL Ontology itself is defined as
<http://www.w3.org/2002/07/owl>, and not
<http://www.w3.org/2002/07/owl#>? The latter (hash URI, ending in "#")
is linked to, via rdfs:isDefinedBy, for all classes and properties,
but the former is the resource described as the owl:Ontology.

Is this really intentional? It seems to conflate the document and the
ontology. And ontologies aren't considered to be information
resources, are they? Neither classes and properties are, nor is the
thing linked to via isDefinedBy (itself not described further in the
document).

Also notice that neither RDF nor RDFS are described like this -- they
both use the hash URI as identifier for the Ontology (also linked to
with rdfs:isDefinedBy from their classes/properties).

Best regards,
Niklas
