Nah, I just expressed myself a little too colorfully.

"wrong" was too simplistic. I didnt mean inherently wrong, I meant 
more like 'one of these sides will be chosen by fiat, and the others 
thereby forbidden.' Which wouldnt matter if the choice were 
arbitrary, but it isn't. So a better analogy might be a law which 
insisted that one drive only at a precise speed while holding the 
wheel with ones right hand, or some such.

That doesnt, but (1) scientific theories are not chosen by standards 
organizations (fortunately), and if they were then it could be so 
described, so your metaphor here is misleading; but more to the point 
(2) there in fact isnt a single *ontological* framework in science, 
and it couldnt possibly be done if there were. Scientists re-think 
their ontologies constantly, without changing their basic Kuhnian 
paradigm. Interestingly enough, the RKF effort is working through 
some genuine sceince in the form of a biology textbook, and one finds 
alternative (and conflicting) ontological presumptions all the time, 
sometimes in the same sentence. We all know what DNA actually is; but 
should we think of (formalize) it as a tube, a spiral, a molecule, a 
linked structure of atoms, a series of pairs, a pair of sequences, or 
as a genetic 'sentence' in base-pair code? The text dances between 
these alternative views without even noticing the ontological shifts 
involved, since human beings can make those ontological shifts 
without effort; but ontologies can't. (Well, not with current 
technology; but to make this possible would be a significant advance 
in AI, not just a standard ontology. The RKF effort might finish up 
using explicit metaphorical mappings, for example, to allow several 
logically incompatible ontologies to co-exist.)

This sounds to me like you are thinking of the alternatives as all 
fitting into some kind of super-heirarchy. As I tried to argue in a 
previous message, they don't really do so ('really' because they 
could be forced into one, but its upper levels would then just be a 
kind of philosophical catalog of alternative metaphysical stances, 
rather than any kind of unified upper ontology in the sense I think 
y'all have in mind.)

I understand your pragmatic point, and even sympathise with it.  What 
worries me is that some of the pragmatic enthusiasts of 
standardization have a very oversimplified vision of what the 
problems are, and that they therefore are being led (or allowed) to 
expect a lot more from the SUO than it can possibly deliver to them. 
If someone thinks of this as being like the choice of a standard 
book-cataloging scheme, or a standard math notation, or a standard 
paper size, then they really havnt understood what ontologies *are*.
