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.
