Abstract:
Imposing one or more usage constraints on digital content involves communicating a digital content data item to a digital content receiver system. The digital content data item includes the digital content and a usage constraint data item different from a digital license data item, or a reference to the usage constraint data item, the use case item being indicative of the one or more usage constraints.
