Information is exchanged with a first repository for storing the digital content and the associated usage rights and for processing a usage transaction specifying the usage rights to determine if access to the digital content can be granted. Information is exchanged with a second repository for generating the usage transaction specifying the usage rights for requesting access to the digital content.
