Absolutely. Fortunately, it is also extremely
useful. Without ambiguity, human communication
would be impractical. BTW, writing long, detailed
ontologies makes names MORE ambiguous, not less
:-) (02)
IRIs are ambiguous *as names*, i.e. they *refer*
ambiguously. They are also however *identifiers*,
and in that role they are, and indeed must be,
unambiguous: the identification mapping is
incarnated by the Web itself, so that http can
work. Unfortunately, discussions of what UIRs
"mean" often gets reference and identification
confused, leading to all kinds of misguided
attempts to eliminate "bad" ambiguity.. (03)
For more on this point, see the following, which
I presented at a workshop on Web architecture
last year. (04)

>natural languages to adapt to any possible subject from any perspective
>for any humanly conceivable purpose. To achieve a comparable level of
