There irony here is that WebFinger itself was created to solve the problem
of resolving an otherwise unresolvable URI (originally mailto and later
acct URIs).  URNs have the same problem, and since they have no
well-defined host, you can't even use WebFinger to resolve them.  I know
there have been some efforts to define URN resolution (rfc2483 et al), but
as far as I know none are very well adopted.  Using HTTP URIs makes the
most sense to me.

But do we really need yet another registry of properties, the vast majority
of which I'm sure have been defined in a dozen other places?  Is there a
reason why reusing one of these existing namespaces would not work?  (and
if something WebFinger specific really is desirable, then we can continue
using webfinger.net, which has already been used for
http://webfinger.net/rel/avatar/ and http://webfinger.net/rel/profile-page/.
 That was kind of the idea of running it as a static site out of the GitHub
"webfinger" org; it's very easy to give others access to everything.
 That's what we've done with activitystrea.ms for several years now)
