RE: URN Madness (was re: Overloaded URIs must GO!)
Hi Dan, Dan said: Would qualifying the DNS name with a date sort this? urn:x-hname:spam.org:1999-05-29:schemata:MakeMoneyFast If I owned spam.org for a week, I could through my life issue hname URIs in this form where there date element fell within the period of my ownership... Didier says: First you don't need to include a DNS domain name in the urn. In fact by doing so you introduce a location dependant context. URNS should be location independent. So, your urn should be: urn:x-hname:1999-05-29:schemata:MakeMoneyFast Algorithm to resolve the name into a location: a) the client connects to a DNS server (this is, in that case the name space respository - let's say its W3C) b) the client requests for a particular DNS record which contains a set of URL attached to a URN. c) The DNS server send to the client a URL collection attached to the URN d) the client uses the URL to fetch the document _located_ at the URL. regards Didier PH Martin mailto:martind@n... http://www.netfolder.com xml-dev: A list for W3C XML Developers.
