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
