Topic: Clarification on Backbone summary elements
Lee Surprenant (Aug 18 2021 at 14:13):
I recently stumbled onto https://chat.fhir.org/#narrow/stream/179190-united-states/topic/Provenance.20-.20what.20is.20expectation.20for.20_summary.3Dtrue.3F/near/249115504
and it got me thinking.
https://build.fhir.org/elementdefinition-definitions.html#ElementDefinition.isSummary says:
Other than Attachment.data, all data type properties are included in the summary form.
Based on that, shouldn't all the children of summary BackboneElements be included in summaries?

I was wondering about the same thing recently & found out that Attachment.data isn't the only exception either: see https://jira.hl7.org/browse/FHIR-33148

I agree with you that, based on usage in the spec, its likely the phrase I quoted was intended for non-Backbone data type.
But I was sort of hoping it could just apply to top-level elements because then our implementation can sit right on top of the _elements filter (which only applies at top level).

I agree @Lee Surprenant that it'd be good if we can fully describe _summary semantics in terms of _elements semantics.
Josh Mandel (Aug 18 2021 at 16:38):
(Like, _summary behavior for a resource an be obtained with the right set of inputs to _elements.)
