Well, to be fair, that layer-cake diagram has become a kind of altar 
decoration, something to be worshipped rather than critiqued. It is 
largely meaningless, as we all know, yet I bet that it is 
incorporated into over a hundred Powerpoint presentations. Ive done 
it myself. If it really is simply BS, let us stop advertising it. If 
it means something ( which Bill and John S. had the graciousness to 
presume that it was intended to) then we might legitimately ask what 
exactly it is supposed to mean. After all, having XML and RDF in the 
base of that diagram seems to represent something very real to a lot 
of people in the W3C, although it is rarely stated very clearly, and 
it has had a very strong influence on the development of the SW 
activity, not always clearly beneficial. Our upcoming F2F agenda has 
that diagram incorporated into its agenda, and one can feel its 
baleful influence stifling discussion already (non-RDF syntax is 
VERBOTEN! Any discussion of 'rules' is OUT OF LINE!! ).

Maybe the Webont group should draw a lesson from the fact that every 
professional ontologist who looks at that diagram is either puzzled, 
amused or horrified.
