Undefined Alias

[markkramerus]

GoFSH is generating this rule, although SNOMED_CT is undefined

* SNOMED_CT#442452003 "Life threatening severity (qualifier value)"

To see the example, use this URL in FSH Online, convert to JSON, then run GoFSH to convert back to FSH:

I am planning to use this example at DevDays, so please give this priority.

But then if you run SUSHI on the version with SNOMED_CT, it runs without error right? I think it is using the SNOMED_CT CodeSystem, which is defined as part of the FHIR spec: https://www.hl7.org/fhir/codesystem-snomedct.json.html

Notice the name, SNOMED_CT

Nick Freiter (He/Him/His) 9 hours ago
So it’s just preferring to use the name of a known resource over an alias

oh, huh, you're right. the rule has SNOMED_CT, and it converts it to JSON in fsh online without an error

Nick Freiter (He/Him/His) 9 hours ago
Yeah if you check the url on the SNOMED_CT resource, it is http://snomed.info/sct. So it makes sense we would resolve that url to the existing resource. It’s a weird special case that that resource is defined in FHIR, but I think GoFSH is behaving correctly here

That is weird. I never would have guessed. Do you want me to close the bug report?

Nick Freiter (He/Him/His) 8 hours ago
Yeah unless we want to do something special for snomed, we can close it as not a bug

I seem to be reporting many not-a-bugs. 🥸
