That's very interesting. The diagram looks a little scary to say
the least. Have people moved some of the semantics "heavy
lifting" into the area of queries and does this point up some
disconnect in the use of ontology itself? I think you raise some
important questions. I'll have a more detailed read over the
weekend in case I am being unfair. (01)
