Using just intersections and exclusions I can get to the fol

Question

Using just intersections and exclusions I can get to the following ```definition user definition folder relation all user relation reader user permission not read = all reader definition document relation all user relation parent folder permission read = all parent >not reader ``` This would give me what I want if a document can have at most one parent But it still feels a bit off

Hey yea maybe like this ``` definition user definition folder relation viewer user | user permission view viewer definition document relation parent folder relation owner user permission read = owner | folder >view ```

LarsRan · Answer

Yeah that is a possibility too But this would mean removing all owners once it is added to a folder

dsieczko · Answer

I don t think you would have to remove an owner unless I m missing something If a document was added to folder now anyone will be able to read and you can keep the owner who will also be able to view

Hi < LarsRan> Were you able to get what you needed using preconditions

LarsRan · Answer

Yes and no preconditions indeed solved the problem of mutual exclusivity but did not fit nicely right now in our current design Now I used the zed definition at the top of this thread and that seems to work

LarsRan · Answer

Regarding the zedfragment you sent I think I might not have made the usecase entirely clear I want all users to have view rights on a document when it is not in a folder when it is in a folder I want only the users with folder view rights to have document view rights
