Re: SUO: Composing Ontologies using morphisms and colimits





John,

Thanks for your summary and comments; I learned something.  I've had it 
on my "To do" list for some time to read up on your work.  

In case this is of interest, the issue of publishing a full account of 
deriving set theory (ST) within category theory (CT) was raised at CT2000 
last summer.  The last word (from Bill Lawvere himself) seemed to be that 
that wouldn't be too useful at this point.  I think he meant that it would 
be best for people to just keep advancing CT and its applications.  If it's 
all that good, its use will eventually become widespread.

Some of us here think we really need more categorical tools in computer 
science right now.  An extended KIF kernel compatible with CT (and that 
computes things such as colimits and colimit-preserving functors) would 
be a welcome addition to our tool set.

To end this rambling note: If you or anybody on your cc list are interested 
in the comments I've received from the CT community, I'd be happy to send 
them along (all anonymous unless I receive permission to use names).

Best regards,
Mike
