How are permissions inherited from community->sub community->collection->item->bitstream
Both from the perspective of how permissions stacks effect
and how do permissions for parents affect default permissions for children if at all?
What does read/write/add/remove/admin mean at each level?
Can I list items in a collection I don't have read access to?
Can I see sub communities of a community I don't have read access to?
What does it mean to be able to add or write to a collection?
Are there tricks for bulk updating security policies for items, communities, collections, bitstreams, etc.
Could some of this be made clearer by hiding nonrelevant permissions at some levels?
