RE: Un-ask the question (was Re: URIs and Names on t
One question I did have while reading the 257 mails on this subject was based on yoour example. I was thinking, with http, your agent knows that it is to retrieve a document - simple and easy. What does it *do* when it finds a URN? (sllightly different slant on the "how do we define it in the first place discussions"). In your case, it returned URL resources ... I started to think (based on some other examples in previous emails) that the general case will be to get a URL for a URN.. In one case the ISBN URN would return a URL gettable document. Of course this won't always be the case. What would URN:car do? I would guess not a lot, but how would we know when it does and doesn't return a pointer to something physical? ISBN might return a URL, but it also represents non-url things - i.e. a physical book. I am working on something just now that is starting to bring up a lot of questions like this. The easy way to go about it is to just say it is an identifier of something - plain and simple. But I get the feeling they can be a lot more useful than that.

It just seems a conceptual muddle BTW, you can get meaningful information about a non-http URN on the web today. For example, Google search for ISBN:1-558-60622-X returns a few pages. If people chose to start publishing comments to either Usenet or web pages about URN:ISBN:1-558-60622-X, you can be sure that they would be accessible to anyone who chose to query. ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://lists.xml.org/ob/adm.pl>
