Type: New Feature
Affects Version/s: 3.27.2
Fix Version/s: None
When creating a new doctype that extends Picture, the Binary metadata mapping (IPTC for example) should be natively working like it does on Picture.
To make the mapping working, the new doctype needs to be added in XML Extension:
<extension target="org.nuxeo.ecm.platform.actions.ActionService" point="filters">
This action shouldn't be needed.
