Create New Role?

[Tôm Ranger]

Hi everyone. As we know, Dataset can be publication by Editor or Admin and I want separate it, Editor only can create private Dataset, create new role "Publisher" can public Dataset for everyone access.

2. All dataset have to create with private visibility(Editor can't change visibility, and it default to private).

3. how to create new role for publication Dataset.

Please guilde me!
