Thanks Chris and team for all your hard work getting this done. I do,
however, have a few comments regarding the OWL ontology. I think in
general the use of domain and range is perhaps a bit "dubious" in that
for many things I think it is overly specified. I can imagine anyone
re-using the Dbpedia properties getting some unexpected inferences from
the domain and range restrictions. Also the range restriction seem to be
done as an OWL intersection so if, for example, something has a
publisher x then x will be inferred to be both a Company and a Person
which is probably not what you want. Personally, in all but a few cases,
I'd be tempted to generalise or just remove the domain/range
restrictions. Any thoughts?

John,
Yes, this issues exist with the DBpedia Ontology, but also bear in mind
this is also why UMBEL and DBpedia have been Linked :-)
Eventually (as per my other mail posts), the DBpedia Ontology will need
to be linked with UMBEL (*which isn't the case right now*) so that it
can benefit from the work done in the UMBEL project. That said, UMBEL is
also a loosely bound ontology for DBpedia already, so you can also
optionally leverage for inference purposes right now. All in all, I am
hoping a lot of the inherent flexibilities that the Internet hosted
Distributed Database we know as the Web accords start to come through
with much more clarity following DBpedia 3.2.
