Simultaneously edit the metadata fields of multiple assets
You can use the batch edit fields call to make the same changes to the metadata fields of multiple assets simultaneously.
This call is particularly useful for editing multi-valued fields because you can use it to add or remove values from authority lists, which appear in the Orange Logic interface as drop-down fields.

“Content Usage” tags become the “Content Usage” field’s authority list
The values available in an authority list are the tags of the specified tag type.
