Extension: Additional Operation Parameter Target Profile

Official URL: http://hl7.org/fhir/StructureDefinition/additional-operation-parameter-targetProfile Version: 5.3.0
Standards status: Draft Maturity Level: 0 Computable Name: AdditionalOperationParameterTargetProfile
Other Identifiers: OID:2.16.840.1.113883.4.642.40.97.42.145

Identifies an operation parameter with a type of Resource for which this resource is to be considered an additional permitted targetProfile.

Additional resources are not known to the base specification, so the operations defined there don't list them in OperationDefinition.resource, or as permitted types for their parameters. These extensions allow an existing operation definition to be supplemented for an additional resource.

This is an draft extension definition; the committee is seeking implementation feedback, and the definition or contents of the extension may change in future versions

Context of Use

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

    Summary

    Complex Extension: Identifies an operation parameter with a type of Resource for which this resource is to be considered an additional permitted targetProfile.

    • url: canonical: Canonical URL of the operation whose parameter this resource should be permitted as an additional type for.
    • name: code: Parameter name with a type of Resource that this additional resource is to be considered an additional permitted targetProfile for.
    • use: code: The 'use' value that corresponds to the parameter being supplemented.
