Minutes

• Question: Should we require all enums in context types to be camel cased? #1265
  • @bingenito introduced the issue and explained how inconsistent use camel-case complicates code in .NET for handling the enums.
  • There as a general consensus that we should not change the existing TransactionResult context at this time, however, it might be helpful to add a note about consistent casing of enumerated values in the API and Context docs to help guide reviewers in preventing additional issues in the future
  • @bingenito to create a PR to add the advice to the docs
• Add property to support analytics across apps #1290
  • @julianna-ciq introduced the issue which has been updated since the initial discussion and there was discussion of the use case and proposed solution.
  • @kriswest checked and received unanimous consensus that the participants recognized the importance of the use case and that a solution should be provided.
  • There was some discussion of the placement of the traceid field as it is metadata about the context message.
    • @kriswest pointed out that there are other proposals on the way (notably from the Identity & Security group) that wish to add metadata to context messages and that it might be better to keep metadata properties to a metadata element in the context. There was some discussion of prior conversations about wanting to avoid confusion with the ContextMetadata object that may be returned with context and intent messages.
    • @Davidhanson90 indicated a dislike for including metadata inside the context message.
    • In response, @kriswest flagged similar feedback from past FDC3 maintainers on the prior version of this issue - and that he recognized that this is an unusual thing to do in the field of Information Retrieval. However, there is also strong resistance to creating additional optional parameters on functions such as fdc3.broadcast and fdc3.raiseIntent as this also rapidly adds complexity to the API. Adding an element to the context object for metadata is, in this case, significantly simpler.
    • @kriswest offered to withhold consensus on the proposal until @Davidhanson90 and @julianna-ciq have a chance to meet and look at other options before we discuss the topic again.
    • It was noted that we need a decision on style in order to raise the proposals from the Identity & Security group.
• Standardize the representation of currency pairs by fdc3.instrument #1291
  • There was only time for a brief introduction to this issue. Which included comments from @openfin-johans on the issue itself.
  • @bingenito and @novavi to invite input from others at their respective firms and @kriswest to raise the topic with the FDC3 mailing list.
• Support for Multiple Application Scopes (Agents) within a single window process #1250 & Question: Disposal/Teardown patterns in FDC3 #1263
  • Not discussed in any detail due to time constraints - @kriswest wished to flag the issue to the community as it will require FDC3 API additions to solve, which are included in the proposal. The proposal will be brought to a future meeting for deeper disucssion.
• Should we split context & intent out of the main FDC3 standard? #940
  • Not discussed due to time constraints - to be brought to a future meeting

Action Items

• @bingenito create a PR to add the advice about consistent use of pascal case in enums in the API (implementation language and context docs (The Context Interface section after advice on union types).
• @julianna-ciq and @Davidhanson90 to meet and discuss Add property to support analytics across apps #1290 before asking @kriswest to include the issue in a future meeting agenda.
• @bingenito and @novavi to invite input on Standardize the representation of currency pairs by fdc3.instrument #1291 from others at their respective firms and @kriswest to raise the topic with the FDC3 mailing list.
• @kriswest navigate Support for Multiple Application Scopes (Agents) within a single window process #1250, Question: Disposal/Teardown patterns in FDC3 #1263 and Should we split context & intent out of the main FDC3 standard? #940 into a future meeting agenda

Rolled over:

• @kriswest @hellosmithy PR to be raised for Context Clearing #1197
