1. A method of managing electronically stored content, comprising: receiving at a content management system a free form ACL associated with an application, wherein: 1. the free form ACL permits definition of an access right other than from a set of predefined options, for a specified user; 2. the free form ACL defines an application-supervised access right; and 3. the content management system is not configured to supervise the application-supervised access right defined in the free form ACL; associating the free form ACL with a content item; responding to a query from the application regarding the content item and the application-supervised access right, wherein the response is based at least in part on the free form ACL and an access qualifying data for a session associated with the query based on user credential data; and wherein the application determines whether a user associated with the session is permitted to perform an action associated with the application-supervised access right based at least in part on the response to the query.
