Interesting analysis of the fragility of SemWeb meta-data. Calls for explicit human viewable and "auditable" meta-data.

Of course, it's hilarious that the SemWeb people haven't yet managed to solve the problem of how to "address" things with URIs. :-) After all, people have been addressing things successfully with URLs for years.

What is apparently difficult is being clear exactly *what* is being addressed. Because SemWeb promises we can be unambiguous about that, but then seems to have problem distinguishing whether we're talking about the "sense" or the "reference".

In contrast URLs have no problems refering because we're not too fussy about what they refer to.

Could there be some kind of "uncertainty principle" here? One which says you can know "what" a thing is or "where" it is, but not both at the same time?
