Abstract: In a retention management scheme, an object, such as a document or folder, is provided with an expiration time in the form of a time stamp attribute. The identification of the security subject providing the expiration time is also an attribute of the object. When the expiration time occurs, the authorization of the security subject is checked. If the security subject lacks authority to delete the expiration time, then the object is maintained on the data processing system and the expiration time is ignored. If the security subject has the authority to delete at the expiration time, then the object is deleted.
