A digital work recorded on a computer readable media for use within a system having at least one repository for enforcing use of digital content in accordance with usage rights associated with the digital content. The digital work includes digital content electronically recorded on a first media portion and being capable of being rendered by a rendering engine, and usage rights electronically recorded on a second media portion and being associated with the digital content. The usage rights specify a manner of use by which a repository will permit use of the digital content. The usage rights can be constructed of a grammar including symbols selected from a set of predetermined symbols which define a valid sequence of symbols that are interpreted by the repository to indicate the manner of use.
