Agree totally: but surely the two can - should - be reconciled? More and
more web services will need unique identifiers to disambiguate such
"subjects" and both people and services need a mechanism to know who
such "authoritative" sources are. Nobody would serious suggest as a
serious service a pointer on a web site that anyone could change: but
what if the service also told you that the source "maintenance
authority" is valid, authenticated (using DigSig) and a community-like
mechanism of "x trusts this source as being authority" - surely that is
the path to establishing a "web of trust"...? (02)

Peter, (05)
Everybody from Linnaeus (1707 to 1778) to the present would agree
with that point: (06)

I also agree that having information freely available on the WWW
is extremely important. But there are international organizations
that have been establishing unique identifiers for decades or even
centuries: units of measure, plant and animal species, chemical
elements, chemical compounds, etc. (08)
I agree that H and O are extremely ambiguous, except in the context
of chemical elements. Therefore, I would prefix those letters
with the identifier for the organization that established that
standard. (09)
If I need a unique identifier, my first choice would be one that
had been firmly established by international agreements, not a
pointer to a web site that somebody could change at any moment. (010)
