Namespaces and URIs (was: A good case for Namespace URIs)
Okay. Once again, the issue of whether a URL used as a Namespace URI should be resolvable or not has come up. The main confusion here is that the URI given looks like a resolvable URL. Most people would look at it and expect it to be able to resolve the URL to some sort of related document. As shown with the govtalk URL though, this is not always the case. But, I can understand the reasoning behind the use of the URL format. It is a convenient and quick way to create a URI that is easy to remember and/or understand (I still don't understand URNs). However, as soon as the "http" scheme is mentioned, people start to assume it is a resolvable URL. So how about this... why don't we just come up with a new scheme to use instead of "http". For instance, we could have "xmlns". Then, when seeing "xmlns://www.govtalk.gov.uk/CR/core" or preferably "xmlns://govtalk.gov.uk/CR/core", we would know that the URL is not resolvable (at least using HTTP). At the same time, organizations can continue to use the URL format for its conveniences. --- Seairth Jacobs seairth@s... (SDML/GTP : www.seairth.com)
