OBI spec is here: https://github.com/microsoft/botframework-obi/pull/128

@JonathanFingold We're merged in all SDKs for this one. Do you need to do anything with Docs for this?

[JonathanFingold]

@mdrichardson @clearab - I'll need a recommended approach to building bots that support this feature, and actionable messages in particular, for both SDK-first bots and Composer bots. (Adding @kaerm )

• On the SDK side, it would seems like an activity handler bot without dialogs would make sense, at least for less complicated bots.
• On the Composer side, I'm guessing custom middleware or a custom channel/connection would make sense, but would not be easy.

PS. Will the protocol doc get copied to the botframework-sdk repo and be public?

[clearab]

I'm going to create some work items for creating (porting really) a sample, as well as documenting. Its in a bit of an odd space, as lots of our partners are documenting this for channel-specific implementations.

[clearab]

I'll leave this open though, and associate those new items back.

@clearab I just noticed that none of the merged PRs for this add triggers for Adaptive, at least as far as I can tell. I came into this one after just about everything was already merged--can you verify that:

1) We want adaptive triggers for this, and
2) If we do, we don't already have them

I feel like this issue is much bigger than I originally understood (adaptive triggers, auth) and could use a second set of eyes to verify where this one is actually at

@clearab Disregard last. I found it in Components/AdaptiveCards
