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.
