# transforms.api.OutputSet

## *class* transforms.api.OutputSet(aliases=None, sever\_permissions=False, description=None) {#transforms.api.OutputSet}

Specification for a list of transform outputs.

* **Parameters:**
  * **aliases** ([*list* ↗](https://docs.python.org/3/library/stdtypes.html#list) *of* [*str* ↗](https://docs.python.org/3/library/stdtypes.html#str) *,* *optional*) – A list of dataset resource identifiers (RIDs) or the absolute Compass paths of the datasets. If not specified, the parameter is unbound. Empty lists are not allowed.
  * **sever\_permissions** ([*bool* ↗](https://docs.python.org/3/library/functions.html#bool) *,* *optional*) –

    If `True`, severs the dataset’s permissions from their input’s permissions. Ignored if the parameter is unbound.

    :deprecated[Deprecated since version 3.85.0: Use transforms.api.Input.stop\_propagating or transforms.api.Input.stop\_requiring instead]
  * **description** ([*str* ↗](https://docs.python.org/3/library/stdtypes.html#str) *,* *optional*) – Output description. Note that this feature is not implemented yet.

### *static* instance(context, json\_value) {#transforms.api.OutputSet.instance}

Creates a parameter instance using the raw JSON value from JobSpec parameters and specific context.

The return value is injected in the transform compute function.

* **Parameters:**
  * **context** ([*ParamContext*](../api-paramcontext/index.md#transforms.api.ParamContext)) – A context object with properties that might be required for creating an instance.
  * **json\_value** (*any*) – Any raw value deserialized from JobSpec parameters.

#### History

* Added in version 1.53.0.

### *property* json\_value {#transforms.api.OutputSet.json\_value}

Returns the JSON value for this parameter to put in JobSpec.

If the return value is `None`, the parameter is considered unbound. If any transform’s parameter is unbound, the transform is considered to be unbound. For unbound transforms, the JobSpec is not published.

### output\_results(instance, \*\*kwargs) {#transforms.api.OutputSet.output\_results}

Generates a map from output RIDs to `TransformsOutputResult`. Results are merged into a `TransformJobResult`.

* **Parameters:**
  **instance** – An object of the type generated by `instance()`.

### *property* schema {#transforms.api.OutputSet.schema}

Returns JSON schema for parameters of this type. Must return a valid JSON schema.
