A "Metadata" item is an item in the database that is present in a tab of the database.
These items make it possible to attach to a screen additional informations that are already present in the database.
That enriches Datacasting.
The configuration will be made upstream to create the tab and all the criteria that can be added to the screen.
Here, the METADATA tab has been created in order to add items with additional information such as the broadcasting studioand the name of the director.
