Hi Robert,
Hey David,

From the TSC call yesterday, my understanding was that the sync call was next week.  Sorry if I misunderstood.
Yeah, it may very much be my misunderstanding, it would not be the first nor the last time that happened.

Nevertheless the content below is something to mull over before we meet next week :) I do believe it provides a very clear solution (and challenges thereto) the problem at hand...

Regards,
Robert

So nobody attented this call today.
This question raised yesterday on ONAP PTL call was the one of release
timing and streamlining alignment with ODL.
The one thing I failed to realize is that ODL release cycle is
off-the-wack due to the major changes happening to yangtools/mdsal
integration.
Judging from the contents of our ONAP-specific distribution (which
really should live in CCSDK or thereabout), ONAP depends on the
following ODL projects:
odlparent
infrautils
yangtools
mdsal
controller
aaa
netconf
daexim
All of these, with the notable exception of DAEXIM, are ODL MRI
projects, subject to having a stable release available at ODL's "MRI
Version Bump Checkpoint".
According to ODL SimRel schedule
(https://docs.opendaylight.org/en/latest/release-process/release-schedule.html
<https://docs.opendaylight.org/en/latest/release-process/release-schedule.html>),
this checkpoint occurs *way* ahead of the official release.
I'll take the blame for Phosphorus and Sulfur completely missing the
deadline, but I fully expect to restore normal service for Chlorine.
What that means in practical terms is that Chlorine (due out
~16.9.2022), the release artifacts for ODL Platform are expected to be
available on or about 15.4.2022 (my favorite day), e.g. full 5 months
ahead of the SimRel release date.
The associated first health checkpoint is on or about 29.4.2022 (aka
Version Bump Checkpoint). ODL release health is further evaluated at
CSIT Checkpoint (on or about 13.5.2022) for a decision to press
ahead or
roll back. A further heal check is evaluated by ODL TSC at "Middle
Checkpoint", e.g. on or about 8.7.2022, which essentially requires all
of CSIT to be healthy or a very good prognosis to be present (otherwise
postponing the SimRel is on the table).
With that, I think the path forward is for ONAP's CCSDK to begin
integration as soon as the MRI Version Bump or CSIT checkpoint, giving
plenty of runway for integration and working out kinks.
DAEXIM is an outlier, we need to come to an agreement around it.

Robert
