I'd suggest this is more a Web Architecture issue than an RDF issue, 
although these topics do tend to surface first in the RDF world.

In the general Web architecture case, I'd also suggest "a" rather than 
"the", since we allow for the possibility that some thing (aka resource) 
may have no URIs, many URIs, etc.

However in RDF as currently defined, each node in the graph has at most 
one URI label. So the situation of a thing having multiple URIs has to 
be graphed using several nodes, and eg. owl:sameAs relations between them.

So the answer probably depends upon whether you're taking about the 
world described by RDF (eg. then we might say "a URI for the resource", 
allowing multiple URIs) or about the detail of an RDF graph itself (eg. 
"the URI label on the node").



Sorry if this sounds angels-on-pinheads!
