Abstract

A method for loaning a digital work having one or more rights associated therewith within a system having repositories configured to enforce use of the digital work in accordance with the rights. A loan right is associated with a digital work and specifies how the digital work can be loaned. If a request for the digital work is valid, use of the digital work is transferred during a loan period from a repository to the requester in accordance with the loan. Loan right data for the digital work is then updated and use of the digital work by the requestor is deactivated upon exhaustion of the loan period.

Claims

electronically associating a loan right with a digital work, said loan right specifying how the digital work is loaned and a loan periods,

wherein the loan right is created from a grammar including one or more symbols selected from a set of predetermined symbols to define a valid sequence of symbols to indicate how the digital work is loaned and the loan period;

electronically receiving at an end-user loaner repository from an end-user requestor repository a loan request message specifying the digital work;

electronically determining at the loaner repository if said request message is valid;

electronically transferring by the loaner repository use of the digital work during the loan period to the requester repository in accordance with said loan right if said loan request message is determined to be valid by the loaner repository;

electronically updating loan right data for the digital work by the loaner repository; and

electronically deactivating use of the digital work by the requester repository upon exhaustion of the loan period,

wherein the requester repository and the loaner repository include both a requester mode of operation and a server mode of operation,
