[ppy] That would be wonderful! Since coming up with some
"ontology-based applications" is one of the goals of our
"ontologizing the Ontolog body of knowledge" exercise, your ISO
18876 talk would definitely expose us to some of the things you
have already thought through that may be pertinent to our
exercise here. I'll try to schedule something with you off-line
and report back to the forum here. (04)
Regards. =ppy
