No. Homophily. http://www.ciadvertising.org/SA/summer_02/chjin/Net_ad/Homophily%20Theory.ht ml It creates/is-oft-noted as localization. I am copying this back to the big list to save myself some repetition. There isn't a general solution to the problem of semantic drift; there is the observable characteristic of homophily where localization (network distance) tends to conserve the set members (Hamiltonian rather than 'strange' in the dynamic). Of course, if one asserts that the namespace URI identifies the set/collection rather than the process/action/policy of the collector, the system is not dynamic. One can chain the observers by degree (ie, a cybernetic control solution) if the cost is sustainable. TimBL and I had this discussion during the http range wars. http://lists.w3.org/Archives/Public/www-tag/2002Aug/0132.html It comes down to the value of keeping the namespace stable vs letting it drift, but while there are good local solutions, none are globally perfect (don't settle into a Nash equilibrium globally because some are contextual (local) or of type RPS (rock paper scissors) and therefore, chaotic by nature). The best the W3C can do is what it does; resort to a second order cybernetic solution and set the meta-policy that the WG for the vocabulary must publish a maintenance policy. For really critical systems, higher order controls (say governments, trading partners) can mandate maintenance policies and validation policies. It is usually a bad strategy to assume a namespace won't change. Chaos is the engine of evolution. The principle of rationality is a weak predictor of human behavior, and as it turns out, certain kinds of games. len -----Original Message----- From: Walden Mathews [mailto:walden@eqwality.com] Sent: Tuesday, February 15, 2005 3:49 PM To: Bullard, Claude L (Len) Subject: Re: Significant W3C Confusion over Namespace Meaning and Policy http://dictionary.reference.com/search?q=homophily Did you mean "homophyly"?
