In the example I show, a note attached to a media record in the blue zone are attached to the media record itself.
A note attached to the red zone are being attached to the object (person, event, place, etc) the media object is attached to. This is what allows you to crop a media record when it is attached to something else. The crop belongs to the other object, not the media record itself.
In events, you cannot see roles with the event record. The role belongs to the person’s portion of the event.
It is hard to explain. But the same principle applies to all objects. What applies to the record itself, and what applies to the other object when the record is shared.
Ah yes, how stupid I am not to have thought about it. In fact if there was a reference counter, the note would display 3 references between it and the place. It’s just that we don’t see this counter and as we don’t see it I thought that only the place was only linked to the note (it is the case but 3 times, one to the place and two to the reference to the two media)
