Thanks for doing this Leslie.

Hmmm. I really think that we should have a standard for URCs, since
they are the means for mapping URNs to URLs and both of those are to
be standardized. Since standardization is the goal, I don't want to
put out a charter saying it is not.

URNs this year and experiment with URC, URAs, ... However, since the
IESG has said "no research!", I think it is a bad idea to write the
charter for the group in such a fashion. Larry can probably comment on
this better than I, but my impression is that we should not expect to
revise the charter every year. We have to do it now because the
original charter is basically complete and just about all of us think
that the group has a lot more useful work to do.

It may be that new working groups will be formed to deal with other
pieces of the UR puzzle. However, we should cross that bridge when
we come to it.

For the reasons above, I oppose dropping this from the charter.
We can certainly argue about timelines.

Re-insert material about standardizing URCs for resource description.
We may also want a line about an informational RFC that lays out the
UR architecture, and another that talks about what is and is
not a URI, thus telling us the sorts of proposals (URAs, URPs, ...)
that are and are not in the purview of this working group.

In an earlier message, Larry said:

: I don't know why we need to wait to discuss what we're going to do
: with URAs. I think there are three choices:
: a) Drop the topic from the WG
: b) Promote them as 'experimental RFC'
: c) promote them as 'proposed standard' RFC
: I don't think (c) is reasonable, so the question is whether you want
: to do (b) in the WG.

I think that procedural methods are a useful way to identify resources,
so I would oppose (A). Looks like we are converging on (B), although
for different reasons. I suggest we change that part of the charter
to state that the URA draft will be discussed and an informational
or experimental RFC issued.

I'm sorry Leslie, but I don't think this last item is possible. Why
should the proponents of the various URN schemes find an interim
solution easier to agree on than a full one? Especially since interim
solutions on the Internet have a way of turning into the one true way?
IMHO, we are better off spending that effort on the evaluation process
you suggest in the previous item.

Why is this last item after Dallas instead of before? Roy, what sort
of time would you like ot put on this?
