New Procedures in API Backlog WG meetings

A number of improvements are under discussion with leadership team of OGW project (Henry), CAMARA Project (Markus), Product Definition WS (Helene) and TSC (Herbert). As of today, the WG adopted agreements are three:

To close the agenda SEVEN DAYS BEFORE the conf. call.
- In case a WG participant wants to include a point in the agenda (e.g., present a new API proposal), this participant shall ensure the corresponding issue is opened in Github by then.
- Exceptional situations will be treated separately.
New schedule of conf. calls **The meetings are to be held by Linux Foundation (Links available at GitHub and Confluence Backlog front pages)
- 2nd Thursday of the month (10-11 CET)
- 4th Thursday of the month (15-16 CET)
Send agenda to TSC mail list, to encourage more TSC member companies to join the call and provide comments when they identify APIs which are of interest for them.

Meeting Minutes within Wiki instead of Github

CAMARA community agreed that meeting minutes would only be recorded in the wiki

Recent Updates & Recap

TSC meeting 18th July:

API Proposal for approval, see https://lists.camaraproject.org/g/tsc/message/206:
- Number Recycling - https://github.com/camaraproject/APIBacklog/issues/54
  - Ricardo provided a sum-up to the API objective.
- Discussion in KnowYourCustomer: Do Tenure API, NumberRecycling API and Shutdown Service Status API fit in KYC Family /KYC SP meeting?
  - Eric Murray raised a point about the complexity to manage KYC (managed by Toshi Wakayama ) as we have now a lot of APIs. We can have probably some 'subteam' meeting. Toshi has raised an issue to discuss this in the KYC WG.
  - User 7d875 asked that these 3 APIs scope have to be clarified to avoid redundancy (example: if Number recycling provide the length of the contract for this number what is the difference with Tenure?)
  - We create the repo for NumberRecycling pointing to KYC but this attachment could be challenged.
User 7d875 There are still some PRs open within the former WorkingGroups repository. Would it be possible to decide about these (stale?) PRs?
- Action Point Ricardo Serrano Gutierrez

Other topics

GSMA informed CAMARA Backlog that Open Gateway is considering certain Drop2/3 APIs that have been stuck in Backlog, “at risk”, due to lack of support. What this means is that GSMA is pushing our MNOs to actively reconsider within the next 2 weeks if they can support them. By raising it in the Backlog meeting we increase the chance to find enough support to “reactivate” progress.

Best Interconnect

For clarity if any API is not a priority for OGW anymore at this point in time, we still expect they can progress independently in CAMARA.

Published new standards, Next meeting (this time) Nick will bring all the documentationa present everything putted together The issue is not eligible to be closed yet.
4	Governance	Adapt Project StructuresAndRoles.MD to changes in API backlog table (reduction of comments) The aim is to update the governing document to reflect on the updated changes on API submission pipeline, according to the new structure of the API backlog table.	Ricardo is currently working on modeling a new table Strugling with the new Table model. Bring the PRs from the old repo Makes sense to bring the table to confluence? GitHub seems to be more accesible and is visited by further people (devs. etc.) The issue is not eligible to be closed yet.
23	TelecomsXChange	New Proposal: Carrier Wholesale Pricing The API template is available in PR#393 First YAML avaliable here	The issue was not treated in this conference call The issue is not eligible to be closed yet. ACTION: Ricardo to reach up TelecomXchange to see if the could connect next meetings
24	Netfocusin Technologies	New Proposal: Steering of Roaming Management The API template is available in PR#398	Does not seem to be in the Scope of Camara. NOt a east west (not between telcos) Already included in 3GPP as technical viable (provided in comment) The issue is not eligible to be closed yet. ACTION: Check for support/commitment from the partners (technical implementation aproach important)
34	China Unicom	New API Proposal: Shutdown ServiceStatus The API tempate is available in PR#32	(relations with device status to be considered) Device Status seems to not fit withion the API proposal, anyhow Yang will be opening an issue to check this May fit better in other API Status based group (Number verification maybe) Wait until is discussed in device status group (Next wednesday 19th at 11h CEST → LINK) ACTION: Open an issue within DeviceStatus subproject to check overlaps. → There should be different APIs (device Status and shutdown services) Number verification doesn t fit either as it is more based in subscription (name change?) Overlap with Tenure and number recycling ACTION: Owner to check Overlap with Tenure and number recycling DECISION Separate Repos should be created but same familiy (KYC) in order to have coordination meeting Pending to complete support for reaching TSC
35	China Mobile	5G New Calling The API template is available PR#31	Not treated Telefonica and Vodafone willing to see the presentation to check whether there is support for this To be treated in next session (still pending for providing extra info)
41	Telefonica	New API Proposal: Telco Scoring The API template is available #42 Input from OGW Drop 4	Presented slides: API-Overview-TelcoScore.pptx The API seems to not fit within KYC and new sg should be created. Support is required, feel free Scoring can be calculated both with any user registered in the telco. Less information means less scoring, Algorithm may be different for each of the implementators (MNO) ACTION: Toshi validate if This APImay fit within KYC API familiy → The issue was rised but still under discussion →(Toshi's proposal 20240627) In API Backlog 20240613 meeting, Jorge TEF and Toshi KDDI agreed that the API does not fit within the existing KYC-SP. Then, in KYC-SP 20240625 meeting, that was shared within KYC-SP and there was no objection. Closed. Pending meeting with DT to seek for support. ACTIONNoel to come back to TEF
45	Telefonica	Scope Enhancement: KYC-Match API -Scoring logic The API template is available #46	This is just an enhancement of the current API. Looks fine as an Enhancement. SHould work without scoring due to limitation in some countries (not all responses include scoring, some cases does not make sense). Optional parameter in the output ACTION: Toshi validate if This API may fit within KYC API subproject ACTION: Scope Enhancement Template should be created → DONE can continue with the discussion Once the Scope Enhancement is approved the README of the KYC sg need to be updated DECISION ALready developed approved in the backlog Action to be closed
50	Verizon	Device Management The API template is available #30	The issue was not treated in this conference call The issue is not eligible to be closed yet.
53	API Backlog	Scope Enhancement Template The API template is available #52	New use cases are usually proposed. Modify the template to show this and approve Consider to close (check if template is merged)
54	KDDI	Number Recycling The API template is available 55	Difference with shutdown service? Check the differences. Shutdown service is not linked to a contract Probable comon scopes with shutdown service + Number reciclyng + Tenure For Tenure two APIs have been proposed and differ from this ones (tenure is more refered the client itself rather than devices or mSISDNS) ACTION: Show the differences/similarities in the next meeting (prepare a slide or two) Check whether Tenure + Shutdown service + Number recycling fit in KYC (parts involved align internally) → Issue is created but no conclusion yet (there should be no problem to fit all the APIs as separate repos will be created just some resources shared) next meeting should be the outcome. Proposal is to include the API in the same API but separate repos DECISION: Move to TSC Consider to close (create repo and include code owners) AP: send supporters email for looking for active code owners
60	Ericsson	New API proposal-Dedicated Networks The API template is available #59	Thorsten presented the proposal: Material here There have been a similar work in a TMF API. Pierre offere himself to Thorsten to reach up DECISION New repo/subproject to be created and a family that groups both NSB and DN ACTION Telefonica providing comments this aafternoon and moving to TSC
61	Vodafone	Scope Enhancement for Network info	Seems that connectivity insigth is more suitable as there is already work done in the Devce Status regarding conection status. As there is more alike a device centric information maybe fits better in device status. Connectivity insights is more focused in the network status As it could be used in both of the contexts a new API may be the best option. DECISION:There is not such a big change for DS subproject so scope could be enhaced and new repo created within the same Device status family ACTION: Create the template in a PR related to 66
63	MTN	New API proposal - IMEI Fraud The API template is available #64	This API was presented already and included in an existing group but no work was done so discontinued. Now Rebecca is presenting the proposal seeking for support DeviceCheck GSMA proposal overlaps this ACTION Chenosis Check the material shared by Eric/GSMA regarding DeviceCheck VDF propose to include it under Device Identifier group, to be validated by Chenosis/MTN
68	Telefonica	New API proposal - Consent URL The API template is available #67	The API proposal was presented, including additional slide info Discussion to follow offline in the issue/PR.
70	Cablelabs	New API proposal - Quality by Design The API template is available #71 Slides available here: here YAML available here: here	New API being proposed to allow 3rd party applications to interact with the access network.

Q&A

How does CAMARA API pipeline work?

The pipeline consists of FOUR stages:
A. Submission of the API proposal.
B. Evaluation of the API proposal.
C. API proposal voting & decision.
D. Sub-Project setup.

The following clauses provides details on individual stages.

Stage A: Submission of the API proposal

Participants: API owner.
Description: The proccess is detailed here. To proceed with the submission, the API owner shall follow these steps:

Fill in the template available here and save it with the following name: "APIproposal_<APIname>_<owner>. md" locally.
Create a new issue in the API Backlog Working Group repository, labeled with "API Backlog".
Upload the filled-in template to GitHub repository folder for API proposals via Pull Request. This Pull Request shall be associated to the issue created in the previous step.

Stage B: Evaluation of the API proposal

Participants: API owner, API backlog WG.
Description: The proccess is detailed here. Upon submission, the API owner will present the proposal in the next API backlog WG meeting, to socialize it with the rest of partners. In paralell..

The WG chair checks that the template is duly filled in. Otherwise, the API owner is requested to provide missing information.
After this sanity check, each WG participant declares their support. If a company wants to become supporter of an API, then a delegate of this company needs to add the company's name in the 'supporters' column in the API backlog table. The more support an API proposal gets, the better (it may get more traction).
When the API owner considers the API proposal is in good shape to go for approval, it informs the WG chair accordingly.
Upon receiving this information, the WG chair merges the Pull Request into the main branch, and sends the API proposal to the Technical Steering Committee (TSC) of CAMARA. This action shall be completed at least one week prior to the TSC meeting where the API proposal will be voted upon.

The whole procedure (steps 1-4) should be done within 2 regular meetings of the API Backlog WG. Nonetheless, it is up to the API owner to decide if it wants to shorten or extend this time period.

Stage C: API proposal & voting decision

Participants: TSC.
Description: The proccess is detailed here. Upon receiving the API proposal and notification from the API backlog WG chair, the TSC studies the proosal and votes it at the next TSC meeting.

NOTE 1: Possible decisions outcomes:

Not Accepted: The API proposal is rejected, and thus will not be included in any API Sub-Project. The TSC will need to inform the API backlog WG of this decision, and clarify next steps: either (1) remove this API proposal from backlog, with objecting companies providing justifications why; or (2) ask for changes (e.g., clarifications, corrections, gaps to be addressed) required in order for the API to be re-submitted by the API supporters.
Accepted: In this case, the TSC shall specify whether the API proposal is to be hosted by a new or existing Sub Project.

NOTE 2: The TSC may also propose changes to an API proposal and take the decision considering these changes. The TSC documents the decision in the CAMARA API overview list (fills in columns TSC date and TSC decision / Sub Project; in case of a No-Go "Rejected" is documented there).

Stage D: Sub-Project setup

Participants: API backlog WG, TSC, CAMARA admin team
Description: If an API proposal is accepted and there is a neeed to open a new Sub-Project, the following steps are needed:

Supporting companies propose their initial maintainers to be added for the Sub-Project. The API backlog WG chair centralizes this information, and sends it to the TSC.
The TSC will use this input to oficially nominate the initial maintainers by next TSC meeting.
The CAMARA admin team creates the Sub-Project repository.

NOTE: After the initial maintainers are nominated, the criteria for further maintainers would be three months of active contribution to the sub project. Code owners are to be decided by the maintainers within the subproject.
