Could you please provide guidance regarding the full set of Language values accepted per the SAFHIR intake specifications for the Formulary and Clinical data? I know that the interop IGs are united around the BCP-47 standard, but the FHIR R4 ValueSet reference at http://hl7.org/fhir/R4/valueset-languages.html only lists a common set. What full set of language codes and/or strings does Onyx accept in clients’ files?
SAFHIR will accept language codes from the full BCP-47 code system. If you look at the language field in practitioner profile of the plan-net IG or the formulary Drug profile in the formulary IG you will see the following:
Language of the resource content Binding: CommonLanguages (preferred) Max Binding: AllLanguages: A human language
the link to the All Languages ValueSet: http://hl7.org/fhir/R4/valueset-all-languages.html
I believe the interpretation of language codes in the base specification is intended to be followed within the IGs.
