Update a curation policy

Update an existing policy.

Note about editable properties: Do not send the entire object returned by GET. Properties like id, created_by, updated_by, created_at, updated_at cannot be set via the API and sending them will cause an error.

Note about waivers: Waivers and label waivers cannot be edited in place. They can be:

• added — send an object without an id but with the content fields
• retained — send an object with the id of an existing waiver
• removed — omit the object

To edit a waiver, remove it and add a new one with the desired values.
