That does sound interesting. I had a sort of "Aha" moment last
week when we were talking about synonyms and heteronyms at an OMG
/ EDM Council event. It struck me that an ontology has formal
definitions of concepts with synonyms, whereas a terminology is a
set of words, with one or more meanings per word, and therefore
has heteronyms. That's why for instance we have no concept of
heteronym in our ontology. Nor (for similar reasons) do we have
No doubt for most people that's this week's glimpse into the
obvious, but it made things come clear for me - ontologies and
terminologies are complementary but different, so any tool that
formally relates one to the other has to be good. (02)
