One embodiment of the present invention provides a system that facilitates issuing rights in a digital rights management system. The system operates by sending a request to perform an operation on an item of content from a client to a rights-management server, wherein the request includes a usage parameter which specifies constraints involved in performing the operation. Next, the system receives a response from the rights-management server, wherein the response indicates whether or not the client has rights to perform the operation in accordance with the constraints specified by the usage parameter. Note that the response may also include a hint that facilitates generating subsequent requests to perform the operation. Finally, if the client has rights to perform the operation, the system performs the operation on the item of content. |
