From what I understand, if I wanted to extract data from a questionnaire and transform it into a FHIR resource such as Patient or AllergenIntolerance, StructureMap based extraction is the most useful for this situation.
Where can I find any examples that demonstrate this functionality?

@Corey Wen you can find an example here which extracts a QuestionnaireResponse to a FHIR Document:

  1. Questionnaire which is refererring to a StructureMap for extraction (Questionnaire in IG)
"extension": [ {
    "url": "http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-targetStructureMap",
    "valueCanonical": "http://fhir.ch/ig/ch-rad-order/StructureMap/RadOrderQrToBundle"
  } ]

  1. StructureMap, IG, depends on base orf map

  2. Sample QuestionnarieResponse

  3. Extracted Questionnaire to Bundle is here

You can do the transform yourself with VSCode, RESTClient http:

@host = https://test.ahdis.ch/r4
POST {{host}}/QuestionnaireResponse/$extract
Content-Type: application/fhir+json

< ./fsh-generated/resources/QuestionnaireResponse-QuestionnaireResponseRadiologyOrder.json

We are preparing this testcase (we still struggle with $populate operation) for the upcoming connectathon and will be participating at the FHIR connectathon questionnaire track ...

@Corey Wen There's another example in the SDOH Clinical Care IG that extracts Observation and Conditions from a QuestionnaireResponse using a StructureMap. You can look for examples in the Artifact Index related to the Hunger Vital Signs (HVS) Questionnaire and it also has the mapping file used to create the StructureMap.
