Agenda

• Approve previous meeting minutes 
  • Approved?
• Overall topics
• Open issues and PRs

...

• Issue: [Geofencing] Support for polygon area type
  • PR: Polygon area type added
  • Discussion:
    • Makes sense from a dev perspective but makes implementation more complicated
    • Possibly we may need this as well for Location Verification, but not necessarily
    • Align schemas with Location retrieval and Population Density in case we accept PR. In the future it would make sense to move it to Common artifacts. 
    • Decision: Keep issue open and discuss there

• Issue: Align security scope with guideline
  • Along with previous issue: Based on the new explicit subscriptions guideline in commonalities, change name of geofencing API to include the keyword subscriptions 
  • PR: update base-path & security-scope for geofencing-subscriptions  → fix both PRs, the old one changing the API name and the new one adapting also event name.

• Issue: [Location-Retrieval]: add POINT as possible Location response
  • Some comments on the issue. Minimum right now is a CIRCLE with radius=1m, Is it not enough?
  • Discussion:
    • Having the radius as 1 does not seem like a practical problem since even GPS often have a few meters of error margin
    • From a documentation perspective clients might think that using a point the precision will be high, which is not the case
    • We don't have use cases for precision lower than 1 meter
    • Decision: Keep the discussion open. Using circle with 1m radius as points seems enough
  • Related with location-verification:
    • Javier asks if the WG is open to lower the 2km minumum of radius for CIRCLE location-verification
    • There were issues open regarding this topic in the past where several problems and discussions raised
    • Javier will open a new issue to continue the discussion

Ongoing

Test plans

• Dedicated Commonalities workshop
  • New Commonalities PR: Enhance API-Testing-Guidelines.md
  • Once new guidelines and consensuated, all test plans will need to be updated
  • For this meta-release it is still not mandatory to have the completed test plans, but the more we have advanced, the better

• PR: Testing plan for location verification
  
  • Used as example for Commonalities Issue Enhancement of the Testing Guidelines, but has to be updated

...

• Are we happy with security scope for geofencing
  • Is it covered by Align security scope with guideline  disccussed above? → Probably, let's double check with Ludovic Robert 
  • Last meeting:
    • Scope name should reflect the data provided by the notification (not geofencing:subscriptions:write but more precise like geofencing:subscriptions:read-location )
    • Discussion on this topic in progress in Commonalities (camaraproject/Commonalities#163)
    • Open pull request in Commonalities update-design-doc-with-explicit-sub-scope-changes by shilpa-padgaonkar · Pull Request #177 · camaraproject/Commonalities (github.com)
      • Proposal is to add scope per even-type additionally to scope managing the right to create a subscription.
    • (Meeting Action): Ludovic Robert will create an issue.

...

• Subscription related issues → Dedicated workshop took place
  

  • Geofencing API - Add Subscription type 'area-left-or-entered' to subscribe to both event in one time

    • Issue in Commonalities Subscription-Issue2: Allow event consumers to subscribe to more than one event types with a single subscription
  • Geofencing API - Defining a standard behavior for first event
    • Issue in Commonalities Issue 140
  • Proposal to tackle open subscription issues Common proposal to tackle subscription-based open issues. · Issue #185 · camaraproject/Commonalities (github.com) - mains points:
    • Align our subscription model with CloudsEvents subscriptions one
    • Introduce a status attribute in the template as we have fair UCs that can leverage this (Retrieve expired subscriptions for monitoring, deactivate a subscription if an user revoked her/his consent, etc...). API subproject could decide to use it or not.
    • Improve the model to allow consumers to subscribe to more than one event types with a single subscription but at least for the first meta-release we enforce to have only event type per subscription. After this first meta release decision to handle several event types in one subscription request should be discussed at API sub projet level
    • Add filters and it's up to API Project to use it. We recommend to be very cautious as it add complexity so it should be keep for very relevant UC.
    • Add initialEvent in config as well to manage request to get event when current situation of a device corresponds to the subscriptions type. .
  • A template yaml is available for review here: Create subscription-notification-template.yaml by bigludo7 · Pull Request #189 · camaraproject/Commonalities (github.com)
