The default behavior in scoopa is full inheritance of all user rights from the parent folder. This can be overridden in the "Add Folder" dialogue. You can also select to inherit the copyright metadata field from the parent folder in this dialogue.
Notice
Inheritance has only a one-time effect. That means once you create a new folder inside a parent folder, all current rights will be inherited. Following changes in the parent folder will not trickle down to the child folders.
