Re: [ippm] I-D Action: draft-ietf-ippm-metric-registry-18 and -initial-registry-10

["MORTON, ALFRED C (AL)" <[e-mail]>]

IPPM,

The WG Chairs have asked me to lead a discussion of the
two Registry Drafts during the IPPM session, and hopefully 
close the extended WGLC. URLs to the drafts are appended
to this message.

The current versions -18 and -10 address the comments on
ippm-list up to today (but see below).

At my request, Michelle Cotton of IANA provided 
yet-another-early-IANA-review, and her comments on the 
-registry-17 draft have been resolved in -18 as well.
*Thanks Michelle!*

AFAIK*, The remaining issue is whether we retain or 
remove the proposed URN namespaces for metric names.
I asked the following question on the list several weeks
back:

For me, the Identifier is sufficient for use in control protocols,
and the unique Name (not URN) is sufficient to document test results.

So, if I have overlooked an issue, please let me know, 
and please come prepared to discuss these drafts.

thanks,
Al, for the many co-authors

* Some editorial issues may remain, as well. At least one of my co-authors
has offered to help find them. We know that the RFC Editor will do a 
more complete review than we can ever conjure-up, eventually.
