Re: [urn] Formal request for URN for ITU

[John C Klensin <[e-mail]>]

A suggestion, partially in support of getting this done rather
than dragging it out further.

Let's take the request at face value: The ITU wants an NID and
namespace for ITU uses, which the General Secretariat will take
responsibility for but T-Sector will managed.  At least in the
near term, the only things that namespace is likely to be used
for are YANG-related.  In the longer term, I hope the ITU will
be alert enough to the possibilities of disruption and confusion
to be careful about what other sub-namespaces might be used an
to consult with this list and others before doing that.

For the particular case of DOI, whether I can see any value in
having urn:doi:10/.... or not, it as clear that, as of now, the
DOI folks don't think so.  It is even more clear to me that
having urn:doi:10/... and urn:itu:doi:10/... and/or
urn:itu:handle:10/... or some other variation would be far worse
than picking on of them.  

Scott, I don't think it is part of the registration or anything
this group needs to discuss, but it would be good to be sure the
ITU understands that expanding the namespace (or creating
different sub-namespaces) in other (non-YANG) directions might
raise interesting issues that, if handled badly, could disrupt
that Internet and/or discredit the ITU, and that some
consultation would be in everyone's best interests.  I hope the
best way to accomplish that does not require me (as an
individual) to drop Houlin ZHOU a note but, if it is necessary,
I believe he would read such a note from me.

If you wanted to guarantee that, you'd put language into the
registration tying its initial use to YANG and requiring
re-review for any updates or changes, but I recommend against
that, if only because some hothead around the ITU would
undoubtedly consider such a provision insulting.

For the present, let's not tie this up trying to sort out
hypothetical possibilities in which there is no present
practical interest.

best,
   john
