Topic: Support for canonical references
Rik Smithies (Jul 26 2021 at 20:40):
Do servers support transactions where the temporary links between resources are not the usual type (reference to an id) but links between canonical references (reference to a url, perhaps with a version appended)?
And how about chained searches/reverse chain, includes and revinclude across canonical references?

Paul Church (Jul 26 2021 at 20:49):
No, the Google implementation does not do any of those. We only handle canonicals in the context of looking up artifacts like profiles, valuesets, etc.

@Paul Church - so I can't search for QuestionnaireResponses based on the characteristics of the referenced Questionnaire? Or include a Questionnaire when I retrieve a QuestionnaireResponse?
Paul Church (Jul 26 2021 at 23:26):
Nope. It's part of the R4 functionality that we haven't got around to implementing. It's called out in the docs as unsupported but no one has asked about it yet - same with reference :identifier and token :of-type.
Ward Weistra (Jul 27 2021 at 09:39):
@Rik Smithies Same seems to be true for Firely Server. @Alexander Zautke says there's no support for that.
Lee Surprenant (Aug 02 2021 at 20:27):
Sorry for the late reply (I'm just back from a vacation), but the IBM FHIR Server has yet to implement handling canonicals like reference search as well. That said, it looks like we've recently started on that feature.
