BTW: is the set of resources discrete or continuous?
If continuous, the set of possible states is infinite (real numbers)
and the problem becomes given a URI is discrete (must
address one and only one resource), can you know if it does?
In short, the URI is a coarse address and the www does
not equal the universe. The WWW is an isolate by definition
but not practically. That is why it may be quite wrong
to say the semantic web is the world wide web. In practice,
they are related but distinct systems.

You can't measure entropy as a state function without declaring
the properties of the system you are measuring. That is
what makes the www-tag debates so onerous: is the www the universe?
1. Is the set of resources equal to the possible
states of all resources addressable by URIs?
2. Is the act of naming by URI equal to the operation of
addressing by URI?
3. Is there a test(s) by which one and two can be
proven true or false?

Fair enough. I meant "noisy channels" in a somewhat poetic sense to
include anything that would degrade the shared assumptions that allow
efficient communication to occur. For example, a future world where
Microsoft Word 2003 binary documents can't be read by widely deployed
software ... the passage of time and the evolution of software would
be the "noisy channel."
But even in literally noisy channels, such as dear old analog modems,
the markup redundancy allowed all sorts of ad-hoc error recovery by
software (e.g. tag soup parsers) .
