Action Item Review

Updates from CAMARA Fund Board Meeting (@Herbert Damker )

  • David del Val took over the role of Juan Carlos García as voting representative of Telefonica

  • We have now two nominated Community Release Managers

    • Samuel Adeyemo nominated by Nokia 

    • Marouane Balmakhtar nominated by T-Mobile US 

  • Markus Kümmerle elected as Chair of the CAMARA Outreach Committee

    • formerly known as Marketing Working Group ... now merged

API Backlog (@joseantonio.ordonezlucena )

  • New sub project for network slicing API (approved on last meeting) created: https://github.com/camaraproject/NetworkSliceBooking

  • Request to approve API Proposal "Call Forwarding Signal"

    • see message: https://lists.camaraproject.org/g/tsc/message/113

    • Proposal presented by Fabrizio

      • Anti-fraud use case proposal from GSMA OGW

      • Indicates if voice call forwarding is enabled for a device

      • Applicable to both mobile and fixed devices

    • DECISION: Approved

      • Jose to provide agreed sub-project maintainers

  • Discussion about not yet accepted "Device Visit Location", see TSC mailing list

    • API requires end user location to be collected and stored for an extended period (30 days)

    • Privacy / user consent issue, as end user must consent before data can be collected and stored, which must start long before API is called

    • Kevin raised issue of possible negative press coverage from misinterpretation on how API would be used, and anti-fraud use case is unclear

    • Anti-fraud use case appears weak, marketing use case may be controversial

      • Device Location APIs give current location, which does have a clear anti-fraud use case

    • Henry expressed view that TSC should not block APIs if technically possible and seen as valuable for some markets

    • PROPOSAL:

      • GSMA OGW product workstream to re-check commercial value of such an API

      • Anti-fraud use case to be reviewed and clarified

      • Remove marketing use case

      • TSC to then agree disclaimer to be included in sub-project repository

Commonalities

  • Update on important topics and request of actions

  • Update from Rafal:

    • Preparing next release (v0.3) with linting rules and API testing guidelines (see last meeting minutes)

    • Discussion about error response format:

      • Current format defined in Design Guidelines, a change would break all API following this format

      • Proposal to use RFC 9457 Problem Details for HTTP APIs for error responses

      • Lot of examples (e.g. from cloud providers) of different error response schema

      • Question: keep current definition or change towards RFC based schema

      • Proposal: request company opinions within the issue. If no consensus raise it to TSC for a vote.

        • Eric will close the current issue and open a new one with the summary of current positions. There comments should be raised.

    • Issue #128 API Design : UNAUTHENTICATED 401 API format issues with some gateway implementations, e.g. having no control over error schema

Identity & Consent Management

  • Initial input info by Diego

  • The moderation role will be handed over from Jesús Peña (Telefónica) to Axel Nennker (DT)

  • Release v0.1 generated https://github.com/camaraproject/IdentityAndConsentManagement/releases/tag/v0.1.0 (will be referenced by Commonalities v0.3.0).

  • OIDC profile first draft provided by Telefonica.

    • High participation - several comments to discuss/agree points on the profile

    • Agreement within the working group: Profile will be self-contained, but will clearly remark every change or deviation with regards to existing referenced standards e.g.: OAuth2 or OIDC.

  • Duplicity of information GSMA-CAMARA: Issue in GSMA already created, PR to follow to remove redundant info

Release Management 

GSMA certification of CAMARA APIs (@Mark Cornall)

  •  

  • GSMA would like a global standard, which includes authorisation flow even if local regulation allows alternative authorisation flows

  • Chris requested extended discussion on common testing issues at next meeting
