Being generic isn't incompatible with being well-founded. I am curious
about what ontologies you looked at and as to why you thought they
weren't well founded. Reading an ontology spec won't tell you what the
authors of the ontology read (and reading your ontology doesn't tell
it either - apart from the DOLCE links). And most of the other
ontologies you cite in your paper are well-founded IMHO. Don't get me
wrong - I think it is important there are different ontologies out
there for similar concepts, representing different views of the world,
and I am therefore really excited about Event-Model-F.

That last point is very interesting - we are running into similar
problems when trying to represent news at the BBC. However, I am not
sure whether it should belong to an event ontology - if multiple
interpretations were modeled in a separate ontology, you could
represent multiple interpretations of a single writing, of a single
document, etc.

Just two small comments: would it be possible to not make the examples
available in zip files? Also, it looks like the content-type of the
ontology is not right. And it would be great if you could put an HTML
spec online - conneg'ed from the main ontology URI.
