The following statement (basically a re-iteration of what you said Stella) is how I see things, and my starting point for design in SKOS: 'The complete intension of a concept should be inferred from the preferred label, the non-preferred labels, any scope notes or definitions, and relationships to neighbouring concepts.' [which is essentially the same as ... (from Stella)] > "concept = preferred term + any non-preferred terms + any scope note + > any clues given by relationships to broader terms and others" The reason I replace 'term' with 'label' is because of the way I have heard 'term' used in the thesaurus world. In my experience, when someone refers to a 'term' sometimes they are pointing to a concept, and sometimes they are point to a string of characters. Actually if you look at Stella's equation, it illustrates my point. In the first part 'term' is used to refer to the character strings (concept = preferred term + any non-preferred terms ...) but in the second part it is used as a proxy for concepts (concept = ... relationships to broader terms ...). I would argue that 'broader' is a relationship of meaning, and therefore a relationship between concepts, never between strings of characters. When I use the word 'label' I am pointing to a string of characters or a symbol. When I use the word 'concept' I am point to some idea in my head. I find that not using the word 'term' helps to keep this distinction clear.
