The data-requirements operation aggregates and returns the parameters and data requirements for a resource and all its dependencies as a single module definition.

The official URL for this operation definition is

 http://hl7.org/fhir/OperationDefinition/Library-data-requirements

Formal Definition (as a OperationDefinition).

URL: [base]/$data-requirements

URL: [base]/Library/[id]/$data-requirements

This is not an idempotent operation

In Parameters:
NameCardinalityTypeBindingProfileDocumentation
target0..1string

The target of the data requirements operation

Out Parameters:
NameCardinalityTypeBindingProfileDocumentation
return1..1Library

The result of the requirements gathering

Note: as this is the only out parameter, it is a resource, and it has the name 'return', the result of this operation is returned directly as a resource

The effect of invoking this operation is to determine the aggregate set of data requirements and dependencies for a given target resource. The result is a Library resource with a type of module-definition that contains all the parameter definitions and data requirements of the target resource and any libraries referenced by it. Implementations SHOULD aggregate data requirements intelligently (i.e. by collapsing overlapping data requirements)

Request: Request data requirements for the CMS146 library

GET [base]/Library/library-cms146-example/$data-requirements

Response: Returned on successful evaluation
