Minutes

• Updating participant CLAs for the Community Spec License
  • An active CLA is required for meeting participation (as FDC3/FINOS considers meeting participation to constitute contribution)
  • @kriswest demonstrated how to check your CLA by opening a a dummy PR and requested all participants do so during the meeting - where a CLA for the new license is not present EasyCLA can then be used to sign a new one.
  • Meeting templates will be updated with information on this - and we'll cover it again at the next meeting in January
• Multiple Language Bindings #990 and Proposal to add .NET interfaces and context declarations #931
  • Details were provided on how to review the proposed signatures and contribution issue and how it is proposed that governance will work (as a part of the FDC3 project itself, rather than a separate project)
    • There was consensus at the meeting that this was the right approach and should be used for these signature and others proposed for adoption.
    • Work is already underway (and ennearly complete according to @bingenito) on adding .NET signatures to the FDC3 documentation - when avaialble these will help enable further review
  • @kriswest, on behalf of the FDC3 maintainers, proposed @bingenito as an FDC3 maintainer (to support the .NET signatures, alongside a number of colleagues from his firm that will wor as contributors) and requested the SWG's consent, which was given.
• FDC3 should avoid union types in contexts and other objects #1105
  • @bingenito & @kriswest discussed why union types are a problem for FDC3 implementations written in languages other than TypeScript and JSON Schema:
    • Its a type of polymorphism that is hard (or impossible, where unions with primitive types are used) to emulate in other languages.
    • It can sometimes be solved in API signatures via function/method overloads - but these can add both cognitive and code complexity or marker interfaces (an interface thats added to multiple classes, just so it can be used as a type)
  • There was consensus at the meeting that FDC3 must avoid such constructs whereever possible if its to be implemented in multiple languages
  • There was consensus that PR remove union type for chat message #1102 should go ahead and make a retrospective change to FDC3 2.1 to remove the union type that fdc3.chat.message contains
• Correction to the 2.0 IntentResult? #1107
  • @openfin-johans & @kriswest described the issue: FDC3 2.0 had (what the authors consider) an error in it. It was intended that Intent handler be able to return void and that intentResolution.getResult() resolve to void. However, as written in the standard docs, an error would have to be thrown (as the IntentResult type does not include void). This was corrected in FDC3 2.1 and was implemented in the FDC3 2.0 conformance tests such that a void result is expected - hence, all FDC3 Desktop Agents that have been tested for 2.0 conformance (3) already use this approach. The proposal is to make a retropsective change to 2.0 to apply that correction.
    • There were no strong objections to doing so at the meeting. It was resolved to move this to a concrete PR and then re-check consensus on making the change.
• @kriswest provided a brief overview of changes to the FDC3 NPM module (2.1.0-beta.4) and work underway to update its build (to be completed before the beta label is removed).
  • Feedback is desired from the community on the new module, which can be used with existing 2.0 Desktop Agent implementations.

Action Items

• All meeting participants: raise a dummy PR (as demosntrated in the meeting) to check your CLA status - for most this will show 'not authorized' due to the FDC3 license update, click to be authorized and then follow the instructions to sign (or have your firm sign) the new CLA.
• @fdc3-maintainers review and merge remove union type for chat message #1102
• ALL test the FDC3 NPM module 2.1.0-beta.4 and report back on any issues - its should be compatible with all apps using the 2.0.x modules
• @kriswest Implement a PR to resolve Correction to the 2.0 IntentResult? #1107
