Model Instance Transformation

OPERATION: Model Instance Transformation

The official URL for this operation definition is:

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

URL: [base]/StructureMap/$transform

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

Parameters

Use

Name

Cardinality

Type

Binding

Documentation

IN

source

0..1

uri

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

IN

content

1..1

Resource

The logical content to transform

OUT

return

1..1

Resource

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

Usage note: every effort has been made to ensure that the examples are correct and useful, but they are not a normative part of the specification.
