The uplink key identifier of the highest license in the chain with an uplink key identifier. If the MediaLicense class contains a root license or a simple license, then this property returns Guid.Empty.

Remarks

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).
