In the real world, people do tend to have an understanding that various editions of Hamlet are all versions of the same underlying work. Obscuring this notion, in the interests of philosophical 'purity' (forgive the caricature!) seems to be perverse - one can't help wondering whether, when a model leads to something so counter-intuitive, common sense might be right and the model wrong. The INDECS definition of a Creation makes it clear that in the Ansel Adams case, the U W is AA's photo of the mountain, not the mountain itself (which I suppose is a 'creation', though some among us might think we had got the capitalisation the wrong way round! ;-) ) Sally How about different levels of reality? One for Adams and one for the mountain. Perhaps one is doing a search for photographers, then the Adams level of reality is valid. Or one is trying to match photographs of mountains with a map. Then the mountain level works. This seems to be in line with what elements and sorts (or search) can accomplish. However, as a new student of DC, I wait for review by others. I guess my reaction is that the UW depends on what you are looking for. Gary Masters Gary E.
