DDI3 Uniform Resource Names: locating and providing the related DDI3 objects

DDI3 Uniform Resource Names (URN) are great as persistent identifiers for DDI3 objects. But an application would need not just a unique name (URN) but the location (URL) of the DDI3 object which is identified by the DDI3 URN. General thoughts on resolving URN's to URL's will be discussed. A distributed resolution system based on the Domain Name System (DNS) will be proposed. Structural details of a web service for providing DDI3 objects will be described.
