My understanding of the semantic web is actually that giving DIFFERENT
identifiers (and as Rich says: "globally unique", "persistent", and
"actionable") to things is a GOOD thing.
Depending on your purpose, two identifiers may or may not be the same.
This is a standard problem, and I believe it is much easier solved if
I have 2 identifiers and separate sameAs assertions. I can use the
existing sameAs as my default, but can easily differ in opinion (by
using contradictory sameAs - which may involve localizing and
modifying the default sameAs, but at least it is solvable.)
With regard to publications:
a) OpenAccess Preprint
b) OpenAccess Postprint
c) ClosedAccess Elsevier Journal
(well, rare to find these together :-) )
have the same ID or not?
For many purposes they are sameAs, but not for all.
However, Rod is correct about the poor history (although I don't
consider LSIDs actionable, they are about as actionable as the text
strings - you can machine-resolve both, but...).
I just thing Rod should call for re-use of identifiers where it is
believed to be identical for all purposes and new identifiers PLUS
sameAs relations where uncertain.
