I agree with Egon that the uniqueness requirement is
rather weird. What it
means is that a thing is only considered an "identifier" if it points to a
database that uses a similar granularity for modelling the world as
Wikidata. If the external database is more fine-grained than Wikidata
(several ids for one item), then it is not a valid "identifier", according
to the uniqueness idea.
Then we should create a Wikidata item for each concept on that
external database.
