| Use | Name | Scope | Cardinality | Type | Binding | Documentation |
| IN | source | type | 0..1 | uri | The structure map to apply. This is only needed if the operation is invoked at the resource level and no structureMap has been provided. If the $transform operation is invoked on a particular structure map, this will be ignored by the server | |
| IN | sourceMap | 0..1 | StructureMap | The structure map to apply. This is only needed when the operation is invoked at the resource level and no URI has been provided. | ||
| IN | supportingMap | 0..* | StructureMap | StructureMap resources that support the source map. If a source URL is provided, the map can be provided in this parameter (or it can be provided as sourceMap). | ||
| IN | srcMap | 0..* | string | The same as structureMap, but the resource is provided in the mapping language rather than as a structureMap. | ||
| 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
