We've seen this even with LC's identifiers -- last year a few people
crawled them due to the budget snafu. This seems like a case for LOCKSS, eh?

Uniqueness, I agree, is an aspiration rather than a reality. If we are
doing well, any of those systems will
- not conflate two entities into the same identifier
- not have multiple identiifers for a single entity
That's the intended "unique" -- rather than "one identifier to rule them
all".

However, I believe that ISNI is bridging between these various sources --
certainly including LC and VIAF [1], and also ORCID [2].

The thing is, the semantic web doesn't require a single identifier. We can
assert that ELM's various identifiers all identify the same entity -- and
*that*, in my mind, is a step forward.

Anyway, to get back to ELM's question: are libraries using these
identifiers? How?

ISNI has reserved a block of identifiers for use by ORCID, so there will be
no overlaps in assignments."
