URCs

[Bigwood, David]

Back in the mid 90's there was a lot of discussion about URCs Uniform
Resource Characteristics. Since then not much seems to have happened.  I
know there are some PURL and Handle systems up and running.  Are there any
UNC systems out there?  It would seem to have an advantage since there is
some metadata associated with the address which would aid in resource
discovery and selection as well as locating resources.

Sincerely,
