4. Review of Today's Agenda

   1. Issue of licensing and code contributions in O-CU gerrit repos
      LF investigated also
      taking an unusual activity for our community, code needs to be removed
      will restart the O-CU project with new, empty repos
      rebuilding is the easiest way to clean up and address all concerns
      re-examining some best practices
      concerns?

   2. Rittwik asked, integrated eNodeB OCU or distributed eNodeB OCU?

      Jack answered, Affects all OCU repos.
      Jack asked, how much OCU is used in this release?
      Rittwik answered, not very much.
      William asked, new contributors in OCU?
      Jack answered, contributors to area of concern have changed; 4G area
      has been reexamined; 5G area has different contributors; focusing on
      5G portion which didn't have code/licensing issues
      William asked, only 4G code is impacted? 5G also?
      Jack answered, going thru process for both as everything is
      re-submitted, adhering to guidelines; LF giving guidance how best to
      proceed.
      John Paul asked, how to capture lessons learned from OCU project,
      publicize to other projects?
      Jack answered, this gives us an opportunity to review best practices
      and make sure people are aware & complying, following well-established
      open source guidelines for all projects, so other projects can avoid
      complications. Rely on contributors to follow guidelines, sometimes
      have to clean things up, taking a strong step to address the
      concerns.
      John Paul asked, these principles and guidelines, where are they
      published?
      Jack answered, the O-RAN-SC wiki has the page, not easy to find,
      https://wiki.o-ran-sc.org/display/ORAN/Best+Practices

            ORAN Alliance?
            Jack M. answered, writeup is being reviewed, process is onerous, have to
            go to board for permission

            request to board

            just one
            Jinri H. clarified, this is for ASN.1; Hank wants to broaden request.
            Current request is from Thoralf targeting specific ASN.1 content in
            one ORAN specification. Want to broaden this to apply to all the
            ASN.1 content from ORAN alliance. Hank wants to improve/refine the
