Question on RDFS3.0 (was Re: proposal - Fragments redux )

(I changed the subject line and removed a direct reference to the ISSUE
to untangle the thread...)

I have a technical question/clarification on


As far as I know (but people who are much more familiar with the
reasoning algorithms than I am can prove me wrong) one of the issues
with OWL-Full is that OWL-Full allows statements on 'itself', so to say.
Ie, I can, in OWL-Full, make a statements on the core vocabulary of the
language itself (I can say that rdf:type is functional, for example).
Among other aspects, OWL-DL makes a strict separation of the core terms
and does not allow any statement changing their semantics (well, they do
not make sense in DL terminology).

I was wondering whether RDFS3.0 cannot include the same sort of
restrictions. Such a variant of OWL might be even easier to handle and
implement without loosing real functionality. Have you guys met any
applications in your practice that would exploit this self-definition

Again, more savy people might prove me wrong in that this is not an
essential problems for, say, an RDFS3.0 reasoner; in which case this
mail is just an extra noise on the mailing list:-)
