RE: quarantining namespaces
I agree with that. But your use and the use of your neighbor may be in conflict. You say your use governs, and as far as the spec says, it does. But practice is, the browser turns it blue and makes it clickable. I believe that it is good practice when using a URL as a URI that one put something where it points for the sake of politeness, or to use URN and be explicit in that document (a URN only has one semantic, to name, so I consider it a document) exactly what is meant. The problem comes of overloading and leaving only contextual clues as to intent. If it is intended only to name: name it. If it is a name with an addressable referent, address it. If it is or can be both, address it (leave a RDDL or RDF file there). Leaving it dangling because in the future one might want to change it is somewhat like letting your 2 year old child into the neighbor's yard without diapers because you don't want to change them soon; or the neighbor letting the Rottweiler into yours because he may want to walk the dog later. Avoid the conflict. Leash the puppies. This should be common practice: a constantly evolving protocol for getting along with the rest of the people in the neighborhood. len From: Paul Prescod [mailto:paul@p...] In my world-view all URLs are URIs. Sometimes we use them as identifiers and sometimes as locations. I also believe that URIs that can be used as both are better than URIs that can be used as only one or the other. HTTP URIs have that property.
