But internic.net itself is a name that doesn't carry any information in it.
You know it's a name for a site on the net in the same way that you
would know a URN is a name for a resource on the net. The metainformation
that you personally know was obtained from someplace else and not from
the name. In your example a footnote is a collection of metainformation plus
probably a URN but not a URN in and of itself.

cerf.sciamer.1992.4.4 contains metainformation that isn't needed. It's
nice to have but it can be gotten by other means. Does the ISBN number for
a book contain the authors name? But with the ISBN number you can find
the authors name plus some more info that will give you the citation your
are looking for.
