Topic: Questionnaire externally defined

Hi Implementers,
I'm new to FHIR and have a question about "http://hl7.org/fhir/StructureDefinition/questionnaire-externallydefined" this is a extension that was autogenerated by the NLM Form Builder. I need to load a external answerlist to a questionnaire item of type choice. The answerlist is coming from a database and is unfortunately dynamic. This url unfortunately leads to nothing. Is there an alternative to the "questionnaire-externallydefined" or a different way i can look into?

That was an internal extension (which should not have used the hl7.org domain) for some functionality from our LHC-Forms internal format. Do not use that, and sorry for the confusion that causes. I think you probably want to use either answerValueSet or answerExpression (which might pull from a "variable" extension that did a FHIR query). You will probably need some intermediate API to transform your database output into FHIR (perhaps a ValueSet expansion).
