Hi, in case you didn't follow DISPATCH, or haven't unpacked from IETF114 yet,<br>
UUIDREV is in the chartering process. I picked a few splatters of<br>
places were there may be interested parties. I'm sure that I missed a few,<br>
so please forward if you think of them.<br>
<br>
The ML is up and some links:<br>

<br>
Jim Fenton and I are co-chairs, and we are meeting today to discuss virtual<br>
interim dates, processes and the like. My preference is to have a regular<br>
(monthly) virtual interims so that we can reach a higher velocity.<br>
<br>
I think the IESG could vote on the charter as soon as next week.<br>
If you are interested in being WG secretary or being a document shepherd,<br>
please let the chairs know.<br>
<br>
Knowing what time zones are involved would be VERY good.<br>
<br>
<br>
that proposed Charter again:<br>
<br>
Since the publication of RFC 4122 in 2005, a number of additional versions<br>
of universally unique IDs (UUIDs) have been proposed. A number of errata<br>
have also been verified against the original specification, motivating<br>
a full revision of the UUID specification with the additional versions added.<br>
<br>
This working group will produce a standard-track RFC4122bis specification<br>
based on limited review of RFC4122 that will include resolution of verified or<br>
held errata and incorporation of the following additional UUID versions,<br>
using draft-peabody-dispatch-new-uuid-format as a guide:<br>
<br>
- Field-compatible version of UUIDv1 optimized for improved database locality<br>
- Time-ordered UUID based on Unix epoch timestamp<br>
- UUID version for vendor-specific use cases<br>
<br>
Other aspects of UUIDs, such as alternative representations and UUIDs that<br>
are other than 128 bits in length, will also be considered and the working<br>
group may produce specifications on those topics. They will not be<br>
considered, however, prior to completion of RFC4122bis, and such milestones<br>
will be negotiated with the responsible AD prior to work commencing.<br>
<br>
Milestones:<br>
<br>
Mar 2023 - Submit RFC4122bis to the IESG for publication as Proposed<br>
Standard<br>
