Okay, how about a better analogy: the telephone system! The telephone
system is the web, the phone number is the URI, the thing that calls and
receives calls is the resource.

The resource could be a person, or an automated system, or who knows what,
but its precise nature does not matter to the telephone system. This is
perhaps a better analogy than the postal system, given its electronic
nature. (Consider the speaking clock, and weather hotlines, and so on).

Hmm, but then what makes it the semantic *web* rather than an inferencing
system or ontology language? Why is the W3C involved? What does this have
to do with HTTP? Why are we even having this discussion? :)

Incidentally, it is interesting to reconsider the example of identifying
galaxies by URI in the light of the phone system, and consider identifying
them by phone number (technically already possible with tel: URIs).

You can do it, and the phone system / web won't care, but if you try to
describe it using RDF and say tel:555-1234 is 100 million light years away
it seems quite confusing.
