Topic: Servers requiring multiple parameters
Michael Donnelly (May 13 2020 at 16:49):
There's something I think we need to put in the spec, but I'm not sure how to word it. Hopefully someone else can point at a comparable example.
I agree completely that supporting search parameters for date, measure, and location is essential. Servers need to have the option to require multiple of these. For example, unless someone is searching by ID, we are probably going to require a measure and at least one of location and period.

How can we express this in an IG?
Abbie Watson (May 13 2020 at 16:54):
That seems to be an issue of push vs pull architecture. The group has brainstormed and agreed in prior threads that both usecases are feasible and of interest. But for the purposes of an IG, it helps to pick one (or both) to be explicit. It's common to provide a sequence diagram in IGs. So, I'm thinking a) define the usecase describing a client with pull architecture, b) provide a sequence diagram, c) document API calls.

We are working toward the specifics of valid grouping of search parameters. There is a mechaism that US-Core used

worst case we just say it narratively.
John Moehrke (May 13 2020 at 16:56):
so, write an issue with the suggested grouping of parameters you think are good.

Abigail. Push is a different transaction from Pull. so there is different transport requirements/expectations
Abbie Watson (May 13 2020 at 16:58):
I agree. I'm saying that the sequence diagrams often capture in their examples when multiple search parameters or headers are required; and at which step.

... That involves an extension on the CapabilityStatement and some generated text
