Re: URI lifecycle (Was: Owning URIs)

*Very* interesting paper, for the content and for the links.   
Addresses many a topic I've been trying to sort out.

If I may ask for a clarification on a few key points at the beginning:

1) At what point does 'minting' occur?  (a) When I think of the URI,  
(b) when I first write it down as a string in some file, (c) when I  
'serve' it in some formal way, (d) when I make a statement that  
references it, or (e) ...? You define it as 'establishing the  
association between the URI and the resource it denotes', but how does  
the process of establishing that association occur, exactly? It all  
seems a little imprecise with respect to real-world resources.

2) Am I correct in thinking the URI owner is just the person who has  
the authority to create a URI (and optionally provide an initial set  
of statements about it)? In the SW, the idea of someone having the  
"authority" to link their URI to the actual resource -- Earth's moon  
for example -- is confusing, since many people will mint URIs meant to  
refer to the Earth's moon; I think they all have that authority, in  
some sense. (AWWW focused more on the actual URI and information  
resources, where there is an implicit association, often through  

3) Can you define a "core assertion"?  If I can improve my assertions  
to clarify that I meant the Earth moon we all know about, as opposed  
to some other 'Earth moon', is that not allowed per R1? How do we know  
when an improvement makes the original concept more useful, as opposed  
to erroneous for some users? (Note your suggestion later that "it's OK  
when expectations are properly set", a la SKOS.)

The paper is a nice encapsulation of many of the idiosyncrasies of the  
current state of the social practice. Thanks
