A set of codes that reflect the relevance of the Questionnaire to the $assemble operation - specifically, whether the form needs to be assembled, whether the form can be referenced as a subQuestionnaire and whether the form can be used as the 'root' of a QuestionnaireResponse.

This Code system is referenced in the definition of the following value sets:

Properties

This code system defines the following properties for its concepts

NameCodeURITypeDescription
Not Selectable notSelectable http://hl7.org/fhir/concept-properties#notSelectable boolean Indicates that the concept is abstract. It can be used for searching, but cannot appear in instances
Parent parent http://hl7.org/fhir/concept-properties#parent code Indicates a parent concept that can subsume this concept

Concepts

This case-sensitive code system http://hl7.org/fhir/uv/sdc/CodeSystem/assemble-expectation defines the following codes:

CodeDisplayDefinitionNot SelectableParent
assembly Assembly needed An abstract code that subsumes all codes for Questionnaires that require assembly prior to use true
independent No assembly needed An abstract code that subsumes all codes for Questionnaires that DO NOT require assembly prior to use true
root Root Questionnaires An abstract code that subsumes all codes for Questionnaires that can act as the root for a QuestionnaireResponse true
child Child Questionnaires An abstract code that subsumes all codes for Questionnaires that can act as subQuestionnaires true
assemble-root-or-child Assembly-required root or child This Questionnaire can be used as the root of an assembly operation or as a child in an assembly process. In either case, assembly is required before use. false assembly, root, child
assemble-root Assembly-required root This Questionnaire can be used as the root of an assembly operation, but requires assembly before use. It is not intended for use as a child module. false assembly, root
assemble-child Assembly required child This Questionnaire is intended to be used as an assembly operation but cannot be used as a root - it must always be a child module false assembly, child
independent-root-or-child Assembled root-or-child This Questionnaire can be used without assembly and be used directly, but is also safe for use as a child module false independent, root, child
independent-child Assembled child This Questionnaire can be used without assembly, is also safe for use as a child module and is only intended for use as a child false independent, child
