Hi Robert,

Robert said:
In other words, although a URL is a unique identifier, it should not
be used as part of the URN, a truly unique identification for that
object.  One last question: If an object is copied, is the URN
supposed to change, or is it supposed to remain the same?

Didier says:
If the copy is exactly a mirror of the original, you can add it to the URL
list associated to a particular URN.

And about the resolver, yes, a HTTP server could be used to resolve URNs as
long as you have the client part that knows where to connect to resolve the
particular name space.
