      1. Running the vote until Saturday.  It looks like Dawn will be the color.
   2. OCU new repo 5G
      1. Jack: As we talked about the last two meetings.  We had some issues with the O-CU project.  Ran into problem where contributors brought in code that they were not allowed to bring to the project.  Since we have cleaned up.  LF decided to drop all code in the O-CU project and focus more on Best Practices and other activities.  It aligns with what's been changed in the O-CU project.  Some new contributors are coming in and we're moving on to the 5G code.
      2. Yingying: For O-CU I have a new repo request 5GNR.
      3. Jinri: Several weeks ago we mobilized a few more contributors on this project.  We will submit a request for a new repo.  We developed a timeline for contributing O-CU code for 5G.  The first patch of code will be uploaded by early next month or the earliest at the end of this month.
      4. Lusheng: The previous code from the Amber release has been purged from the repo.  March 17 there was a new repo request.  Do you want to withdraw the previous request? 
         1. Jinri: The request was raised in March is a part of the restart process.  Thank you for this reminder.
         2. Lusheng: This request is still outstanding.  We will send this out to the main mailing list.  
         3. Jinri: I approved two.
         4. Jack: I want to review for this approval.  Some of the TOC were not included.  This is trying to restart the process with new code and contributors.  We will restart the process focused on 5G.  This code was not in the previous contributions.  We are working closely with contributors to tighten up the best practices and process.  We need to create a repo to restart this process.  Are there any questions?
            1. Ganesh: We are re-writing all the code?
            2. Jack: The code will be 5G O-CU.  Yingying is still the PTL but we are working with a new team of contributors and new code.
            3. Jack: Request a vote to approve a new O-CU 5G repo 
               1.  Vote to approve a new O-CU 5G repo

   2. Action/ update on Intel license agreement on binary usage 
      1. Jack: People may remember as part of O-DU in Bronze doesn't have layer 1 open source contributed at this time.  Intel has offered a binary image of their flex ran software to be used for the O-DU low.  We have been tied to that binary license for testing O-RAN purposes.  We have been trying to have a review with the Intel.  We are hoping for Bronze release to have a test instance of O-DU with Intel binary as a part of that.  There is still progress.  We are looking for contributions and activities for feedback and guidance.  It still has to go for the O-RAN legal team review.  Remember that's not Open Source Code.  The O-DU project is organizing that.
         1. Zhimin (Intel): we will provide a doc file in the O-SC community.

8. Standing Agenda Items (Brief Status of Ongoing Activities)
   1. Release Manager Trishan de Lanerolle /Release Planning: Weekly TOC Scheduling
      1. Project Bronze Release
      2. Jack: Looking at our release plan.  Today is the 4-15.  That is dev 4 sprint ist sprint 3.  We are well into the development cycle process.  We have a week and a half to move into ETE testing and interoperability.  Looking at Jira items.  People testing software it is important to work issues between O-CU high and O-CU low.  All the modules need to work with the self test for the capability of the ETE use cases and the progress on the use cases.  Important to have documentation.  Looking at C release with Cherry I have restructured the table to reflect the Maintenance release to give folks a chance to get their backlogs items completed.  This is in Cherry even though it's Bronze release.
   2. user-59b16 Requirements Software Architecture Committee
      1. We are tracking the Traffic Steering use case closely.  Working with Viavi for metrics.  Ron is enhancing the E2 simulator.  That will get worked into this last sprint.  Matti has the TSxApp to make progress. Regards to healthcheck Martin and John.  Speaking to Eliza the healthcheck is getting more ellaborate if youre making changes check back with John Ng and David Kinsey.  If you're making large changes.
      2. John: John Ng is aware and is happy.
      3. Eliza: John will finalize the documentation, right?
      4. John: Yes, OTF documentation is coming together nicely.
      5. Eliza: We worked with Martin for healthcheck2.  Once we have the interface spec for healthcheck 3.  In the mean time the team was working with other information.
      6. John: Let us work together.
      7. Matti: Please keep me in the loop for the A1 healthcheck.  I need to know.
      8. Jack: The question is with all of that work is it staying aligned with the specs coming out of the O-RAN working groups?
      9. Rittwik: Not sure.
      10. Jack: I am making sure we are staying aligned.
      11. Martin: Yes, we try to keep aligned problem WG is 3GPP.  It looks similar but it's not with 3GPP.  I am directly in contact with 3GPP modeler.  There is good progress on the yang model.  This is a major step.
      12. Jack: Did you add that link?
      13. Action/ Martin Skorupski add the link for the yang model to the wiki.
      14. Martin: I wrote a script that will pull the yum models.
      15. Eliza: We need to document what we are doing.  We want to do it incrementally so we are in synch.  Also operators and vendors are supposed to create the tests.  It is important to provide the test team with instructions.
      16. Jack: it is important to carry evolution forward incrementally.
      17. Tracy: We are within working group 1 in the O-RAN Alliance.  We are forming a formal pathway to get the data models from O-RAN to 3GPP so there is version control easy to download data models.  That will be worked out in WG1 and properly documented.
      18. Jack: Do you see there will be yang models beyond 3G-PP.  
      19. Martin: We already have them.  Fronthaul Yang files are in gerrit for modeling.  Also from IXRAN to O-RAN.  They are available for the software community.
      20. Jack: is there an easier way to organize.
      21. Tracy: A reason for O-RAN Alliance we brought in the 5G baseline model from 3GPP and in parallel numerous 3GPP Yang models in need of repair.  They are upstream 3gPP and augmenting 3GPP.  I think we're going to have the repo reside where it is right now and allow access to the O-RAN software community.  We don't want to proliferate.
      22. Lusheng: What license are these under?
      23. Tracy: We are working one on one with the operator liason with 3GPP.
      24. Lusheng: Whether oran alliance 3gpp the question is are we hosting those models?
      25. Tracy: We won't host it on O-SC.
      26. Lusheng: Yes, we don't have to host it if it is in github.  We can just pull github.
      27. Martin: They don't have a license statement on github so we asked them to add their licenses for the yang models.
      28. Jack: the new ones that are generated in O-RAN where are they going?
      29. Martin: It's the decision of O-RAN Alliance.
