 ==== Permissions and Roles ====
+MongoDB has a role based permission model. We use this for ''polyDB'' to organize read and write access to the collections.
+For each collection there are two roles, one with just read access, and one with write access. For a collection //collection// in the subsection //subsection_one// of section //section// the two roles are
+  * ''section.subsection_one.collection'' for read access
+  * ''section.subsection_one.collection.admin'' for write access
+(there may be more (or no) subsections in the list).
+For public read access to the data there is one role ''polymakeUser'' that inherits the read access roles of all public collections. This role is assigned to all users. In addition, a user can get assigned read access roles of non-public collections and write access roles to collections she or he wants to modify (add, delete or replace documents, edit the schema and meta data, edit the documentation).
+For general public access there is a user ''polymake'' that only has the ''polymakeUser'' role and password ''database''. With this user you can log into the MongoDB instance runngung the ''polyDB'' and read all public data.
+Creating roles and users, and assigning roles to users requires MonoDB the ''user admin role'' built into MongoDB, and thus is limited to administrators of 'polyDB''. Contact us if you
+  * want to start a public or private collection
+  * want to give other people access to your private collection
+  * want to make your private collection public.
