We stick to the 4pm Helsinki time slot for this meeting. Note that Europe will switch to summer time on March-26. So, for people not doing the switch at the same time, the meetings after March-26 start one hour earlier. Reminder for participants from the US: The US already switched to summer time on Mar-12.

1. Every time: Check rule RC-4 (link) that all L or XL commits of the last two weeks have also new unit tests. This is our policy. link-to-reviews (gerrit filter instructions // gerrit t-shirt-sizing).
   1. Last checked on 2023-02-28
      
      1. https://gerrit.o-ran-sc.org/r/c/ric-plt/xapp-frame-rust/+/10405 how automated CI module testing can be done is to be discussed // also need to discuss CI // already known that this requires discussion with LF
         1. 2023-02-28: Abhijit worked with Matt and Sridhar from LF on this. Jobs are now running, but they fail. There's a credential issue. Abhijit to remind Sridhar. Once this is fixed, we can change Dockerfile to install prerequisites.
      2. https://gerrit.o-ran-sc.org/r/c/ric-plt/submgr/+/10287 → waiting for test cases, Gunja know and will update test case.
2. every second time: Review code coverage stats and blocker code smells
   1. We take a look at the two links in the beginning of this page: Code coverage reports..
   2. The list below is only working reports // Anybody volunteering to work with LF on making the code coverage CI to work again (there's still the old JVM version)
   3. Thoralf did this last on 2022-05-27. 2022-11-22: we did not do this this time

   21. anybody would like to get more familiar with RMR?

4. 2022-12-13, 2023-01-17: Bin Yang asked about O2 for RIC platform deployment and xapp deployment. Need to discuss on this topic. O-cloud is deployed in AT&T and Taiwan lab.

   1. The current platform deployment scripts might not be in line with O2 envisions
   2. David Liu (WR) asked from James on O2 as well. James to check if a proposal on using X testing framework could also be used for integration. There's is also a link to robot test cases.
   3. O2-D(MS) is relevant to RIC platform.
   4. deploying xApps (LCM) is also an O2 issue - the alternative of using CRDs is not implemented in OSC RIC. Could be implemented as second option for deploying xApps.
   5. 2023-01-31: No news yet
   6. 2023-02-14 No news yet, Thoralf received e-mail on this from James. Still to check.
   7. 2023-02-28: some e-mail discussion. Ball's on Bin Yang & James side. Subhash and Thoralf discussed this and Thoralf to call a meeting with Bin Yang, subhash, James, Thoralf.
5. James:updates?
   1. 2023-01-31:
      1. working on existing robot test cases (that integrate xapps and platform) to be part of xtesting tests.
      2. Subhash asked for a wiki page documenting this work.
      3. WR also want to contribute to xtesting for O2. CNF package definition still open and concept of DMS.
         1. discussion with Bin Yang in this meeting is possible. Maybe some proposal would be good.
         2. Tacker-based deployment needs to be checked.
   2. 2023-03-14: TODO
6. Sunil updates?
   1. 2023-03-14: TODO

      1. Kserve adapter (mentioned in RSAC and e-mail from Hoejoo),
         1. 2023-01-31 Joseph presented the kserve part. We agreed as working assumption to go for solution #1 (slide 2) with model-based inference. Comments by e-mail to Joseph. Slideset: link
            1. Thoralf to create JIRA item for this
            2. Subhash/Thoralf commented that ricdms cli and REST should be implemented at same time. But also ok if only in one.
            3. 2023-02-14: Subhash discussed with Hoejoo on this (internally) - maybe a presentation coming later
            4. https://wiki.o-ran-sc.org/plugins/servlet/mobile?contentId=67535114#content/view/67535114

   1. Abhijit is now committer for the rust subsystems (platform and xapp) - but there seem to be issues on LF side that didn't actually made this happen.
      1. Thoralf raised support request to LF. Reminders sent. Still no solution.
   2. 2023-03-14: TODO

   1. 2023-03-14
      1. TODO
      2. RIC-967 (RIC subscription delete required related changes in xApp communication) added to H release. We discussed this in a meeting and decided to implement pre and post notifications aligned with RICARCH.
10. H release content
    
    1. we mark items that you are >90% sure (=”committed”) to work on during 1H2023 with your label, like subteam-n (Nokia), subteam-s (Samsung) and so on. Items that are proposed for H release but not “committed” we mark with subteam-n-proposal, subteam-s-proposal and so on. To ease usage I created a couple of filters for follow up. See §7.3 from Jira usage conventions.
    2. Sprint dates
       1. Sprint H release dev sprint 1: Feb-20´to Mar-12
       2. Sprint H release dev sprint 2: Mar-13 to Apr-2
       3. Sprint H release dev sprint 3: Apr-3 to Apr-23
       4. Sprint H release dev sprint 4: Apr-24 to May-14 (last planned development sprint)
       5. Sprint H release dev sprint 5: May-15 to Jun-4 (only for unplanned last-minute development items)
    3. We go through the rough views on what you might want to work on. Also as input use delayed items from previous release link
