Topic: groupingId in ImplementationGuide
Paul Church (Apr 29 2021 at 19:16):
In the published CARIN BB IG, the ImplementationGuide resource has values like "_term_valueset" and "_ex_example" in the definition.resource.groupingId field.
This is not valid FHIR. That field has the Id data type, which is limited to a regex of [A-Za-z0-9\-\.]{1,64} so underscores are not allowed.
I verified this with https://inferno.healthit.gov/validator/ and it returns errors for all of these values.

I am afraid I am not seeing what you are referring to. I have placed the content of STU1 ImplementationGuide-hl7.fhir.us.carin-bb.json into the Inferno validator and it did not return any errors.
Can you please provide an exact citation of what you are seeing? Please include the file, location, and quote.

I downloaded http://hl7.org/fhir/us/carin-bb/definitions.json.zip
From this zip I extracted ImplementationGuide-hl7.fhir.us.carin-bb.json
I copied the entire contents of this file (one ImplementationGuide resource) into https://inferno.healthit.gov/validator/
It returns 113 errors, all of them basically the same issue:
ImplementationGuide.definition.resource[86].groupingId: id value '_dyn_capabilitystatement' is not valid on line 1.

The Google implementation of validation agrees with this and returns a similar error
Corey Spears (May 03 2021 at 03:26):
I can reproduce the problem with the file you mentioned. This is quite odd because it does not show up in the ImplementationGuide-hl7.fhir.us.carin-bb.json file from http://hl7.org/fhir/us/carin-bb/full-ig.zip
There are no groupings or groupingIds in that file. I am not defining any groupings in the IG input (using FSH), so I have no idea why these are showing up in the definitions version of this file. I will have to dig further.

@Paul Church Cross-post. Looks like it is a core FHIR issue.
