I doubt many people have been that 'URIs will solve their problems' in 
the sense implied by John's statement. What they've likely been told is 
that, compared to other identification mechanisms, HTTP URIs have very 
nice characteristics and so are a good choice in many scenarios:    (02)

1 - HTTP access
2 - globally unique
3 - already in use and relatively well-understood (companies Web pages, 
XML/namespaces, etc.)
4 - not industry- or organization- or country-specific
5 - easily reused across industries, organizations and countries    (03)

and therefore a good *URI strategy* can solve a lot of data federation 
problems because you get it more or less 'for free' when using languages 
such as RDF/OWL. The point is only that it *does* solve some problems 
that other identification mechanisms do not. For example, if the ISO 
committee responsible for quantities and measures would publish *the* 
URI for 'kilogram' then everyone else on the planet could use it, or at 
least map to it, quite easily and guarantee complete interoperability 
wrt that concept. Of course, there's analysis work to do wrt what the 
interesting concepts are ... but then that's obvious, isn't it?    (04)
