Al et al.,
	While I think the characterization of the concept is good, as the
URIs do actually *are* a description of a concept. However, where the use 
value of a URI for a concept is because the concept itself, not a  
particular description of the concept, is denoted by the URI. The key 
issue in my mind here is interoperability - so you *can* of course use 
any URI to denote any concept or description of a concept you want in your 
RDF theoretically (I mean, I can make an RDF statement saying http://www.google.com denotes the 
string "green cheese", and can create my own URI  http://www.example.com/green 
cheese which I say denotes "google"!) and you  can give them separate URIs
 - but what does that buy you? It seems that's what people want to know is 
that if I have URIA and you have URIB, does URIA denote the same thing as 
URIB - and feel free to replace URIB and URIA with the words "metadata 
about URIX". Henry and I's analysis believes a sort of "equivalence class" 
or statistical approximation of an equivalence (it's 80 percent likely URIA
denotes the same thing as URIB) created either by hand of via a search  
engine is the way to go, thus Web Proper Names.
