There are many statements in Wikidata nowadays, but they get really
"trustworthy" through references (other than "imported from
Wikipedia").
But for external IDs, references are superfluous; they are their own
reference, by definition. So how about marking IDs with a "verified" (or
"last verified on") qualifier? Much of such work could be done by bots;
we could then filter the problematic ones out for manual verification.
As we have no control over external lists, this would have to be
re-checked ever so often; but, again bots to the rescue.
Yes, I fully support this proposal.
What do you think about making "last verified on" not a qualifier but (part of)
the reference information? The reference could state where the bot has looked up the ID
and give a time. This would be somewhat similar to what is now used in Freebase Ids, e.g.,
in
https://www.wikidata.org/wiki/Q42.
In general, it might be useful to have such a "last verified on" property that
can be added to arbitrary references. There are many other uses for this. One common case
would be that a user has changed the value without even being aware of the reference --
then one would be able to detect this automatically by comparing the last modification
time with the "last verified on" date.
Putting the "last verified on" into the references also makes it possible to
have different dates for different references there.
