Cool. :)

Well it depends. You can store the initially minted URI, just
like you need to store the UUID. Technically, there is no actual
difference. But I prefer to suggest UUIDs because they remove any
temptation to derive them from other properties of the resource
or to interpret them as something other than an opaque token.

No. The lack of such a mechanism for the _general_ case is the
entire point of UUIDs. :-) They are opaque names, not addresses.
Of course, if you want to provide a custom lookup mechanism for
your UUIDs, that’s your prerogative.
