Dear Mike, (01)

MW: We did this in a data model rather than OWL originally, though there is
now an OWL version. Still there is no use of equivalence. There is a
difference between something that is a pump and something that is a
collection of letters "pump". One may be used to represent the other, and
other collections of letters e.g. "pompe" may be used to represent that as
well, probably in this case by different language speakers. (03)

MW: Indeed, which is why we separated words from what they represent.

MW: No. One theory, just the (possibility at least) of different
representations of that theory. (06)
