Magnus also pointed out that many external IDs

that they are their own reference. The situation is somewhat similar
for homepages. Should we adopt the practice of giving a single
retrieved value (without any further information) as the reference for
such cases?
I'd use the reference URL the value was imported from together with the
retrieved value.
Yes, that's a good point. Even if an ID has a value for "formatter URL"
that defines the URL, it might be good to record the URL that was used
to verify the data, since the formatter URL might change. Especially
bots should add this, since it's no extra work for them. However, a
single "retrieved" value is still better than nothing there. For
homepages and other URL properties, I would not maybe store the URL
again in the reference.
Note that most often the reference is not where the value is "imported
from" but simply an external reference. In many cases, we have imported
data from Wikipedia but it is then verified from another dataset.
