Minutes

The meeting covered a number of small maintainence PRs that are in-flight and assigned reviews to maintainers (see action items) and briefly revisited some open issue in need of PRs
This was followed a Q&A session clarifying some of the FDC3 for the Web proposal prsented at OSFF the previous day and touching on the work of the Identity and Security group.
- A participant asked if there is work underway to represent currency pairs in FDC3 as they need to use them? They are currently inserting them into the id.ticker field of the fdc3.instrument type. They also stated they were considering using an alternative standard because of this.
  - @kriswest stated that there is no currently open issue on that topic, but also provide an overview of how you create one (start by opening the issue and describe your needs). As an opensource project, it's upto the participants to raise issues for additions they want and (ideally) to contribute effort to achieve them - although in this case the maintainers are likely to help - as we're part way through refining the process to contribute context types to the Standard (via docs generation from the schemas).
  - @openfin-johans provided some additional context from the original Financial objects working group on how the existing types were created.
  - @kriswest also demonstrated the context Standard's field conventions, which reference ISO 4217 code for currencies and indicated that it should probably be updated to also cover (and standardize the format of ) currency pairs.
- A participant asked about proprietary context types, unlikely to be relevant to anyone outside their firm and was referred to the namespacing section of the context overview https://fdc3.finos.org/docs/context/spec#namespacing
  - Firms can create, document and govern their own types independently of the standard, the only hard requirement is that they should be javascript objects with a type field that has a string value, which should be appropriately namespaced (don't use fdc3. as thats for standardized types).
- Is FDC3 for the Web always interactive with a server?
  - @kriswest No, it uses HTML Standard APIs to achieve communication locally with a DA running in another window or frame. However, it also supports communication with an adaptor or proxy to a DA which could then be running on a server/in the cloud. I.e. it's a flexible approach and designed to support different formats of Desktop Agent.
- A brief overview of proposals from the Identity & Security group was provided and related to the FDC3 for the Web proposal on the issue of app identity: FDC3 for the Web proposes a basic, temporary identity validation procedure based on the a set of origins detailed in an appD record or extracted from the start URL - but is expecting to adopt asymmetric authentication if/when proposed by the identity & security group (trying to avoid doubling up on similar additions).
  - There was some discussion of identity validation of an app by a DA and a DA by an app, as these are not covered by the current identity & security proposals, which seek to achieve signed communication and encrypted communication between applications via a TLS-like asymmetric cryptography approach, which will require publication of public keys (via an appD record).

Action Items

[x] @openfin-johans to review #1236
[ ] @mistryvinay and @finos/fdc3-maintainers to review #1233, perhaps extend to other types that need id or name docs adding.
[ ] @mistryvinay and @kriswest to arrange to meet and progress the context docs generation PR.
[ ] @finos/fdc3-maintainers review and merge minor project infrastructure fixes
[ ] @kriswest @hellosmithy PR to be raised for #1197
[ ] Issue to be raised for supporting currency pairs as an id type in fdc3.instrument and the context Standard's field conventions.

Rolled over:

[ ] @bingenito & @kriswest to complete PR #1108 and submit for review - to include at least a basic version of supported platforms content (to be improved later)
[ ] @kriswest & @mistryvinay look at #1151 and consider taking over final changes (which include deleting existing context docs, hooking up script to auto-generate as part of build and making sure existing URLs do not break)
[ ] @kriswest & @julianna-ciq rework issue #1142 to reflect the other use cases and update the proposed change based on the discussion
