Subject: RE: [soa-rm] RE: [ontolog-forum] RE: [soa-rm] latest Draft of Concept Map / N-ary Documents specification?
Rex said: "I would actually prefer if concept maps stayed informal or relatively informal for usefulness in my brainstorming process before moving on to my personal process for noodling out constraints." This has been identified as a problem since it leads to different people interpreting things differently. <Rant> For example "A uses B" How would *you* answer the following: 1. Can A exist without B? 2. Is B aware of A? 3. Is A aware of B? 4. Is the reciprocal relationship "B is used by A" true? 5. Does B need at least one A to exists before it can exist? 6. Is B a complete concept without A? 7. Does A always use B? 8. add transitive, reflexive and all variants.... ... I have avoided use of cardinality but others think that cardinality exists in concept maps. Does this relationship mean exactly one A and one B must be present for the concept to be complete or does it represent multiples. I have seen concept maps with plurality such as: "machines are used by workers" Why is workers plural? Does it imply that there must be more than one worker? What about instance, parent relationships? </Rant> While you may answer these very clearly, the exact interpretation is not ubiquitous and YAMMV. Duane
