Good point, when there is no context the proposal is to describe returning an empty context:
{
"timestamp":"2018-01-08T01:40:05.14",
"id":"wYXStHqxFQyHFELh",
"event":{
"hub.topic":"https://hub.example.com/7jaa86kgdudewiaq0wtu",
"context":[{}]
}
}

Would an empty array make more sense than an empty object inside an empty array?

Would a more elegant answer to this negative issue be that the query for current context should be removed in favor of placing the responsibility for communicating initial contextual information into the SMART app launch parameters (as the spec already says) or, in the case where SMART isn't used, as contextual parameters communicated as part of the launch process (but is outside of the spec) ?

Could it be that you still want to get the current context even after launching? I’m thinking e.g. when you think communication failed for some reason.

In conversation with @NiklasSvenzen , @lbergnehr , and @wmaethner:
We see three possible options here:
1) Context passed during launch, in launch specific scenario (as described above).
2) An API call to Query-for-Current-Context, which returns the previous context and can be called at any time.
3) Upon subscription get last event.Overall, the addition of this Query-for-Current-Context web service is pretty complicated. The absence of an event, but the presence of context doesn't really make sense.
Proposed resolution: Persuasive with Mod
Proposed resolution comment:* We will remove the "Query for Current Context" and clarify that the subscriber SHALL receive current contextual information in the form of SMART launch parameters, or if using an alternate launch mechanism, in that launch.

The absence of an event, but the presence of context doesn't really make sense. The community does not yet have enough implementation experience with this web service to justify it going into our STU version of the FHIRcast specification.

Based upon need, we will revisit the existence of this capability.

Eric Martin points out that the exchange of Observations and Observation states
- The Hub should exactly maintain state for each subscribed client. For launch/simple stuff, this is trivial. For more complex scenarios, the client needs to receive the whole set of events.Wouter - if current context is an imagingstudy related, does that clear previous events? Patient vs imagingstudy relationship? We should always send the full context for a sync event [and not create a need to infer context based upon previous events].
Jeremy - If the ImagingStudy.open event changes the patient, why have named events at all? Yes, we should be pushing the whole context (including the patient). FHIRcast should simply ensure that the patient in an external system in focus should be brought to the foreground in my system. Eventing makes Hub implementation more difficult. Being able to extend, AI-based measurements into reports is important.

Being able to extend, AI-based measurements into reports is important. If "Query for Current Context" returns only last event and not "full state", this API would not be as useful.
@gkustas - a getLatestEvent function seems useful. Would be okay removing for further discussion. Would simply want to know what patient/study are open. We oughn't lump draft measurements into this one method.
Topics for further analysis:
- What is the difference between _state_ and _context_?
- How should FHIRcast enable draft measurement exchange?
- ... ?
