Tasks objects have a metadata parameter. You can use this parameter to attach key-value data to tasks.
Metadata is useful for storing additional, structured information on an object. As an example, you could store a video's unique identifier in your system on its content moderation
categorization task. You can also use it to denote the end use-case for the task, as "content moderation" or "data categorization" for example.
Metadata is not used by Scale (e.g., to affect how the task is done).
