Document how to pre-populate metadata fields. The goal is to read any available metadata created by the system and use it to pre-fill corresponding user-editable metadata properties. Or pre-fill values from a static resource. This way editors don't need to fill all fields by hand. This is a common request for image uploads. For example, you might want to pre-fill the Publisher or Rights fields with the company name or the current user's name to ensure that they are not left empty.
