They have though differently for years. Net effect, yet another basis 
for confusion re: AWWW, RDF, Linked Data etc..

Names identify things.

Identification is an act of interpretation that binds denotation to 
connotation via some kind of indirection mechanism.

All of this predates the Web.

It just so happens that URIs are ingeniously designed such that you can 
have an HTTP scheme URI that has interpretation delivered gratis (even 
though this is clearly unrecognized by most, hence the endless confusion).
