[tdwg-tag] Re-organisation of TDWG Ontology: Danger silence will == acquiescence!

I think this is a good idea. However, I would be more specific about what
compliance means. Perhaps the most future proof is something like: "The
ontology must be valid OWL DL as determined by the Manchester owl Lint
plugin to Protege 4." Probably this is equivalent to requiring
determination by the Manchester WonderWeb OWL validator.
The biggest recurring problem I've had with identifying the OWL species of
TDWG ontologies is that frameworks try to resolve some of the legacy DC
terms to the old versions of DC, many of which are not OWL DL for relatively
simple reasons. Try, e.g.
WonderWeb, which quickly indicts some older DC that can easily be
replaced with the 2008 versions.
(It also finds some similar lint in TDWG owl files).
Aside from that, I remain silent, in agreement with Gregor.
