Sure, but those are URIs which are primarily used to identify the  
information, not the topic of the information or the thing the  
information is about. Another important principle that Alan might want  
to endorse is, don't use the same URI to identify a thing and a source  
of information about that thing. And don't say that one of them is  
owl:sameAs the other. To paraphrase Korzybski's famous maxim, the  
website is not the territory.
