I'd vote for admitting a URN is not a URI: a rose is a rose is a rose,
but the one growing in my garden isn't the same rose as the one
growing in your garden, and the one that is in bloom today isn't the
same as the one that was blooming last week (paying homage to your
black hole analogies by adding time into the "location" mix).
