Abstract: A system and method for enforcing rights expressions specifying manners of use of an item, include specifying by a potential recipient of an item a first rights expression indicating a first manner of use of the item proposed by the recipient; specifying by a provider of the item a second rights expression indicating a second manner of use of the item proposed by the provider; determining if there is a correspondence between the first rights expression and the second rights expression; and applying a rule to a determined correspondence between the first rights expression and the second rights expression to determine if the recipient should be granted use of the item.

Abstract: A system and method for processing a rights expression for association with an item for use in a system for controlling use of the item in accordance with the rights expression. A rights expression is specified in a conventional manner in an original format. An intermediate format of the rights expression is generated based on at least one of syntax information and semantics information associated with the original format. The rights expression specifies a manner of use of said item for enforcement on a device. The intermediate format can be converted to a device specific format or a simplified format for resource constrained devices to permit rights enforcement on various devices.

Abstract: A system and method for enforcing rights expressions, include specifying a repository rights expression indicating a manner of use of an item at a repository; and associating the repository rights expression with the repository.
