Below a list of changes to repos (new ones, as well as deletions) under the RICP (near-RT RIC Platform) that we would like the TOC to approve. Parts marked with RICP/RICAPP are proposed by Matti and I (PTLs for RICAPP and RICP) and parts marked with RICP only me as PTL.
(WE1) Project RICP
ric-plt/resource-status-manager
- Summary: Implements the management of Resource Status messages over E2
- Description: The Resource Status Manager is responsible to control the generation of
Resource Status messages sent by the RAN to the RIC by issuing Resource Status Requests.
The RSM provides an API that allows to start and stop the generation of these messages as
well as to issue specific request commands. The RSM provides also default values which are used
whenever a new RAN (eNB) is added to the RIC.

We (RICP and RICAPP PTL) would like to remove the following repositories:
ric-app/demo (empty)
ric-app/reporter (not maintained anymore for 6 months (and actually confusing community if someone uses this as reference) and e.g. the measurement campaign xApp can replace it)
com/asn1 (an ASN.1 compiler for which we found that it causes to much issues that we had to troubleshoot. We already switched to using com/asn1c (which is derived from https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_vlm_asn1c&d=DwIFAg&c=LFYZ-o9_HUMeMTSQicvjIg&r=Tnwenk7t78Qk7cMlMZ90EGmbng6eVuV4yQNhqbtpKkk&m=xoq2zMpPhab9uHOEBVXWXAFXjPsyFpAgdbNtyADOnwY&s=Rkl10dXpdSlyLJTKlTd3zwy98meppgWMQ_0PNWZ8QjQ&e=)(WE3) Project RICP
new repo: ric-plt/ric-test
- Summary: RIC platform-specific testing that are not specific to a single RIC component
- Description: This repo includes test cases that span the full RIC platform, i.e., that cannot run against a single RIC component. This may also include
simulators related to the E2 base protocol, or related abstract test xApps (that do not actually implement 3GPP specifications). Note that the test
cases must still be limited to RIC platform only. If you want to write/check test cases that integrate also other O-RAN SC components, check
the it/test repository.

new repo: ric-plt/ric-dep
- Summary: Code and configuration files that are needed for deploying a near-RT RIC platform instance
- Description: This includes, for example, helm charts for RIC platform components. In this we can make assumptions about the underlying k8s already existing or
we can also spin up blueprints for such a deployment. Note that this component is intentionally limiting itself to the RIC platform and does
not include other O-RAN SC components. For such you might want to look at the it/dep repo managed by another O-RAN SC project.

- Initial committers: (first one AT&T, the other two from Nokia): Lusheng Ji (lji@research.att.com) , Prabhu K ( prabhu.k@nokia.com ) Ranjit Angajala ( ranjit.angajala@nokia.com )Note that this needed for legal reasons to clearly define the scope of the near-RT RIC project. It is aligned with a "scope" wiki text that we wrote for the same reason.
Also note that we continue with the it/dep repo as a general integration repo where any O-RAN SC components can be integrated together. In scope of their work on
integrating all O-RAN SC components, engineers working on the it/dep repo might re-use some of the functionality that was original committed to ric-plt/ric-dep .(WE5) Project RICP/RICAPP
We would like to remove the empty ric-app/uemgr and instead create a new repo under ric-plt/. This is in order to clearly link
the demo xApp to the RIC platform project. At the same time also note that the license of this is changed to a documentation
license. So that its legal scope reflects its actual role in the RIC platform. Naturally there will continue to be actual xApps under the
RICAPP project. Placing it under the RICP project (and not RICAPP) allows Nokia to contribute to it. The name is intentionally kept
generic. As part of this change we also move this page https://urldefense.proofpoint.com/v2/url?u=https-3A__wiki.o-2Dran-2Dsc.org_display_RICA_UE-2BManager-2BxApp&d=DwIFAg&c=LFYZ-o9_HUMeMTSQicvjIg&r=Tnwenk7t78Qk7cMlMZ90EGmbng6eVuV4yQNhqbtpKkk&m=xoq2zMpPhab9uHOEBVXWXAFXjPsyFpAgdbNtyADOnwY&s=gaI_Yvwbqi4X3KKgd2KlO1cau-oPGsKTpA0lo3SzHeo&e= to the RICP project (a reference
in RICA continues to refer to it.
deleted repo: ric-app/uemgr
new repo: ric-plt/demo1
- Summary: A simple demo xApp running on the RIC platform.

We delete the following repo: ric-plt/ue-nib . The scope of the RIC platform does not include this functionality. If, then
such functionality should be developed outside of the RIC platform, e.g., under the RICAPP project. Some of the earlier functionality (read and write
of the demo data that is actually needed in the "demo1" demo xapp (under documentation license) is moved into the demo1 repo as it is
closely related and does not make too much sense as standalone documentation repo. Note that this implies that the functionality is now under
document license in ric-plt/demo1

- Request for adding committers for the integration and test open frame work.
Dear O-RAN SC ToC,
We would like to request the addition of two more committers to the it/otf Gerrit repository to help completing the Amber release target.:
ORDWAY, ADAM G <ao8347@att.com>, LFID ao8347;
MEILINGER, JUSTIN <jx088j@att.com>, LFID jx088j.

- On motion made by user-d3360
- Seconded by Jinri Huang
- VOTE: Vote taken, item passed
- Action/ user-d3360 send Jinri Huang the count of committers.
- In the building how much code is residing?
- Source code repo is a recipe. The source code is not imported into the repo. It is the recipe that puts it there.
- During build time the upstream.
- Is the resulting build unique to our project so O-RAN SC will use that work.
- Yes, it is optimized kernel and the packages.
- Be careful in impacting all of our other resources and projects.
- How often do you need to rebuild this?
- No, we want to build once per release or patch releases. Maybe one or two times per release should be good.
- Concerns about managing the resource consuming job. Work with Lusheng to schedule time early in the process so we can be efficient in the resources across projects and not block others.
- Yes, it is optimized kernel and the packages.
- Is the resulting build unique to our project so O-RAN SC will use that work.
- Lusheng - tonight will provide the full report at the f2f.

- New Agenda Items (New Business): New Items Submitted (+speaker) & Open Call to TOC For Additional Items
- Jun Hyuk Song binary seed code submission.
- We thought seed code is possible through open source. Binary is not an option on the table. We are reluctant to open our code to binary code. We learned binary code is being submitted by another vendor.
- Jack - This is a rich topic for discussion. In open source the code is open and people can look and contribute. We've had discussions with companies about including the binary code as an option. Binary code is not a contribution to the open source community. However binary code can be used for integration and test. For example Intel wanted to keep their layer 1 software. They didn't have to contribute that software. Instead they are contributing a loader module that will pull in their binary from their location. The process to get their code is consistent. The open source community doesn't treat it as open source but instead uses it for test and integration. In this case the O-DU could choose to license from Intel and build it into their process. Intel would contribute the loader. The binary itself is not open source. The company would have to deal with Intel directly for their binary. They are not open source but are build, test, and integration options. The build APIs are open source.
- Jinri - Do we need to discuss this with the O-RAN legal team?
- The broader issue for us is that it is hosted by the Linux Foundation. These contributions aren't in source code. Theoretically, if you could contribute binary it would have to under one of our two licenses meaning people could use it. That is not their intent. It is best for them to keep their code under their management. If we use it for integration and test then O-RAN would have to set up how to make it available for us to use.
- Jun Hyuk Song TOC membership. There are open vacancies for the TOC membership.
- Jack - We want to promote open source developers. Interest in a viable candidate to contribute open source code.
- Jun Hyuk Song What about xApps? Are there requirements for that?
- Jack- We didn't put a hard requirement on contributing magnitude of code. Demonstrate your interest in the activity and the community.
- We thought seed code is possible through open source. Binary is not an option on the table. We are reluctant to open our code to binary code. We learned binary code is being submitted by another vendor.
