I realize that this prolly ought to be on the uri discussion list rather than here, but I'm not there, and there's been some discussion here, at least. I understand that a URL is-a URI by definition (RFC 2396). According to that, URI is the superset of URLs and URNs. So, okay. The URL specification (check the abstract in RFC 2718) specifies both a syntax and a semantic--a URL is a "compact string representation of the location for a resource that is available via the Internet." In the usage of namespaces that claims that the namespace identifier is a URI, not a URL, what *is* that namespace identifier? The URI spec doesn't say that URIs are a collection of things that have the same syntax as URLs and URNs but possibly different semantics. It says URLs and URNs. So, if the namespace identifer has the same syntax as a URL, but not at all the same semantics (because it isn't actually a locator), then is it a URI at all? And if one wants to divorce namespace identifiers from the location semantics, wouldn't it be better to use URNs? Amy! -- Amelia A. Lewis alicorn@m... amyzing@t... There are two major products that came out of Berkeley: LSD and BSD Unix. We don't believe this to be a coincidence. *************************************************************************** This is xml-dev, the mailing list for XML developers.
