7.7.11.1 Model Instance Transformation

The transform operation takes input content, applies a structure map transform, and then returns the output.

The official URL for this operation definition is

 http://hl7.org/fhir/OperationDefinition/StructureMap-transform

Formal Definition (as a OperationDefinition).

URL: [base]/StructureMap/$transform

URL: [base]/StructureMap/[id]/$transform

This is an idempotent operation

In Parameters:
NameCardinalityTypeBindingProfileDocumentation
source0..1uri

The structure map to apply. This is only needed if the operation is invoked at the resource level. If the $transform operation is invoked on a particular structure map, this will be ignored by the server

content1..1Resource

The logical content to transform

Out Parameters:
NameCardinalityTypeBindingProfileDocumentation
return1..1Resource

The result of the transform

The input and return are specified as 'Resources'. In most usage of the $transform operation, either the input or return content is not a valid FHIR resource. In these cases, the return type is actually a Binary resource. For this operation, the Binary resources may be encoded directly, using a mime-type, as shown in the example. Note: this specification does not yet address the means by which the servers may know the correct mime types for the various content involved
