I think I would just change the ontology: "domain
name" (Q32635) should
not be a subclass of "unique identifier" (Q6545185), but rather an instance
I've done that; but it has only reduced the number of results to 3,456
- what else needs changing?
Consider, for instance:
an "instance of" a "telephone numbering plan" (Q103903)
(Actually the uniqueness is
debatable, I don't think DNS is meant to enforce any uniqueness at all,
as it is very common for a website to have multiple domain names.
Surely the uniqueness works in the other direction? A UID identifies
one unique subject; the subject can have multiple UIDs.
