OPERATION: Questionnaire

The official URL for this operation definition is:

Generates a Questionnaire instance based on a specified StructureDefinition, creating questions for each core element or extension element found in the StructureDefinition.

If the operation is not called at the instance level, one of the identifier, profile or url 'in' parameters must be provided. If more than one is specified, servers may raise an error or may resolve with the parameter of their choice. If called at the instance level, these parameters will be ignored. The response will contain a Questionnaire instance based on the specified StructureDefinition and/or an OperationOutcome resource with errors or warnings. Nested groups are used to handle complex structures and data types. If the 'supportedOnly' parameter is set to true, only those elements marked as "must support" will be included.

This operation is intended to enable auto-generation of simple interfaces for arbitrary profiles. The 'questionnaire' approach to data entry has limitations that will make it less optimal than custom-defined interfaces. However, this function may be useful for simple applications or for systems that wish to support "non-core" resources with minimal development effort.

URL: [base]/StructureDefinition/$questionnaire

URL: [base]/StructureDefinition/[id]/$questionnaire



A logical identifier (i.e. 'StructureDefinition.identifier''). The server must know the StructureDefinition or be able to retrieve it from other known repositories.


The StructureDefinition is provided directly as part of the request. Servers may choose not to accept profiles in this fashion


The StructureDefinition's official URL (i.e. 'StructureDefinition.url'). The server must know the StructureDefinition or be able to retrieve it from other known repositories.


If true, the questionnaire will only include those elements marked as "mustSupport='true'" in the StructureDefinition.


The questionnaire form generated based on the StructureDefinition.

Open Issue: Ideally, extensions should be populated in the generated Questionnaire that will support taking QuestionnaireResponse resources generated from the Questionnaire and turning them back into the appropriate resources.



Usage note: every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification.
