But that re-use is tightly bound to the original locating power of retrieving documents using HTTP URLs. Using Google to look up information on URNs isn't nearly as useful unless someone's built a URL-based description. In short, while using URLs as identifiers may be a good tactic in some situations, taking that use as grounds to claim that the Web is built on URIs rather than URLs is a grotesque overreach. -- Simon St.Laurent Ring around the content, a pocket full of brackets Errors, errors, all fall down! http://simonstl.com
