Very tentative suggestion: Would it make sense to augment the normative Namespaces rule on character-by-character comparison with a health warning: "NOTE: although namespace identity is determined on a character match basis, users are strongly discouraged from intentionally creating distinct namespaces named by URIs that would be considered equal per RFC 2396 or other governing specifications." Or some such. Indeed, this might be generalized to a principle that would apply in any similar situation where layered equivalence rules expose the risk of false negatives: you define normative equivalence at the appropriate level, but non-normatively discourage use of names that would result in false positives per higher-level equivalence rules. If practical, this might avoid the need to debate how we would provide RDDL for the two separate namespaces http://example.com and HTTP://example.com, since we've already suggested that the existence of one preclude the use of the other. So, if you really want to play such games and create both, go ahead, but don't ask us why the rest of the architecture doesn't do everything you want after you've ignored our advice. ------------------------------------------------------------------ Noah Mendelsohn Voice: 1-617-693-4036 IBM Corporation Fax: 1-617-693-8676 One Rogers Street Cambridge, MA 02142 ------------------------------------------------------------------
