RE: Un-ask the question (was Re: URIs and Names on t
Hi Mark, Mark said: Repeat after me; URLs are nothing more than URIs with a resolution mechanism. http://www.markbaker.ca is as much an URN or URL as urn:markbaker (once I register it with Netsol, er, I mean IANA 8-). It's just that the former is well deployed, but the latter is not. So the choice is not between URLs and URNs, it's between the devil you know (deployed HTTP URI scheme resolution), and the devil you don't (DDDS). If you expect URN namespace registration to eventually be any less of a quagmire than ICANN, or any more "location independant" than DNS, then I've got a, well, quagmire to sell you. 8-) Didier replies: No Mark, a URL is a locator and you may use it as a "name" with the inherent problem of location dependence. Hence, if you move the resource its name is changing which counter the goal to provide an "invariant" identification scheme to a resource. However, you can say that being a practical mind living in a frozen world (i.e. the web which is about the same as it was 5 or 6 years ago, just bigger) You use what's already there and accept all the inconvenience attached to it. In that case, I agree, this is adaptation to reality. Said that, a rose is a rose is a rose. A location is a location is a location and a name is a name is a name. I finally agree with my ET that he'll have to wait until human beings are more evolved enough to make this distinction. But in practice I agree with you, in a frozen world we have to adapt with what's already there as long as long as we don't mix things. When I use my bike because its more convenient during times of staled traffic I do not call my bike a car :-).
