An uplink key identifier is used in license chaining. To link the elements in a license chain, each leaf license contains an uplink identifier, and the value of the uplink identifier is the key identifier of the next license in the chain, the root license. For more information about license chains and leaf licenses, see Digital Rights Management (DRM).
