The usage rights and conditions can include symbols selected from a set of predetermined symbols which define a valid sequence of symbols that are interpreted by a non-centralized repository to indicate the manner of use for enforcing use of digital content and the conditions. The manner of use can specify how an authorized party is able to render, use, make a back-up copy, conceal or delete the digital content or create a new digital work on a device on which the digital content is stored.
