HI Adrian & all,

yes, I can see your point and indeed, if a rule system was around, it
may do the trick in simple cases. Another (non-exclusive) approach is
what I briefly mentioned at the F2F: is the development of a kind of an
intermediate layer between RDFS and OWL; a layer that would allow some
extra information to be added to the knowledge base without forcing the
usage of a DL reasoner. There are several approaches for this, and we (I
mean, W3C) may want to look into this more closely next year...
