From: "Martin Bryan" <mtbryan@s...> . As Len Bullard > pointed out, http://www-ksl.stanford.edu/kst/what-is-an-ontology.html > defines ontology as: > > "definitions associate the names of entities in the universe of discourse > (e.g., classes, relations, functions, or other objects) with > human-readable text describing what the names mean, and formal > axioms that constrain the interpretation and well-formed use of > these terms". "Ontology" in general means the study of forms, as a branch of metaphysics, the philosophical study of things beyond science and mathematics (e.g. the basic pieces of mental or analystical furniture, such as "substance/accident" or "essense" or "property" or "class" or "type" etc.) and has a long history. "An ontology" as defined above is a more specialized usage. Cheers Rick Jelliffe
