Extension: Extract - Allocate new uuid

Official URL: http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-extractAllocateId Version: 4.0.0-ballot
Standards status: Draft Maturity Level: 0 Computable Name: ExtractAllocateIdExtension
Other Identifiers: OID:2.16.840.1.113883.4.642.40.17.42.84

Allocate a new uuid in a named variable for use in extraction. This is usually used to set the fullUrl for a resource in the output extraction bundle, and then referenced in other resources within that transaction bundle (via fhirpath expressions).

Context of Use

This extension may be used on the following element(s):

  • Element ID Questionnaire
  • Element ID Questionnaire.item
  • Element ID ElementDefinition

Scope and Usage

This extension currently only applies to either the definition or template extraction processing.

The value will be made available as a named variable in extract fhirpath expressions, and only within the scope of the item that contains the extension, and any child items of that collection.

When defined at the root of a questionnaire, the value will be available for all items in the questionnaire (and only allocated once).

When defined on a repeating item, the value will be new for each iteration of the item in the QuestionnaireResponse answers.
