Certainly this is important. But what about "shared language" on the
semantic web ... how does one really define what the semantics of a given
URI is, in a formal sense. It seems that unless this is done in an
unambiguous fashion, any formal infrastructure built on top is sort of like
rearranging, err straightening, deck chairs ...

I wonder if the semantic web can meaningfully work without some of these
assumptions. An actual example of a working semantic web application that
doesn't make some of these would be helpful in convincing me otherwise.
