Media type support

I 'don't understand the issue reported. Need reformulation and/or actionnable elements.

I created a Taxonomy ("Organization").
Then, I created a CT ("Page") and some Users and these ones have a reference field to the taxonomy, as "Permission by field". In this way every user can edit own nodes considering the value of the taxonomy.
Finally, I created the same Taxonomy reference field in a Media Type ("Image"), but in this case different users can't edit different medias.

I would manage nodes and medias with the same business logic thanks to Permission by field, but I am not able.

I hope I was clearer and that I get some help.

Thanks.

This module uses the node access system. So it can only control access to node, not on others entity types, as media.
