Yes, once one has a good idea of what needs proving. Otherwise, like proving that a bumblebee can't fly, one is modeling from axioms, and the bee just goes about its business doing what it will. Abduct, induct, then deduct. Markup scales where it needs to first, in the applications which its inventors had in mind. Note, DTDs were added later. Formalization was done later. This is historical even if not necessary. In short, don't wait on proofs nor ignore them when available. Just be sure of what is being proved and that it is relevant to the task. To the point: is a wall-to-wall XML database the right solution for any problem? No. Can we define in advance all of the problems it is or is not applicable to? Not all. I agree with you 100% on that. As noted elsewhere, when looking for the proofs, it is not XML that needs to be compared, but the data models. As others have noted, there is lots of work being done on these. Meanwhile, hybrids rule the niche today. I do note that the environment for which XML, (not markup) was designed or adopted from SGML, is one of decentralized and loosely coupled sources, not one where normalization is the norm. Will that create update problems? You bet. Like 404, it is a cost of using the system. The only proof 404 needed was 50 years of trying to get around it. Progress in fielding very large distributed hypermedia systems was made only when that constraint was relaxed. The way around the update problems so far is hybridization and tightening the coupling. The ideal of full decoupling is not just risky, it is unworkable to date. You're right about Curie. One shouldn't bet the farm for a prize in husbandry, or die of the experiment, but there would be no Wright Brothers without Lilienthal. len From: lbradshaw@d... [mailto:lbradshaw@d...] Awww, now, gee whiz..... doing a math proof can be as exciting and exhilarating as any other form of discovery, and doing so first can save one many stubbed toes, later. After all, Codd's proofs led the way, as did Knuth's, and were not derived from existing advanced art but from theory and science. While it probably goes both ways, some proofs coming from experience and others derived purely from theory. saying that waiting on proofs makes me a cave man who is frightened of tomorrow is just personal. Which is something I will not respond to, :), other than to say that if Curie had done the math, used the full scientific method, waited for results and included advancements from other scientists, maybe she would not have died of radiation poisoning. Thanks!
