summary method for managing a transaction right on a digital rights management server, method for supporting a transaction for a right to use a digital content item, device on a digital rights management server for managing a transaction right, apparatus for supporting a transaction of a right to use a digital content item, computer executable instructions for managing a transaction right, and computer executable instructions for supporting a transaction for a right to use a digital content item provides a method for managing a transaction right on a digital rights management server. The transaction right is the right to a transaction of a right to use a digital content item. The method comprises the steps of obtaining an attribute associated with the digital content item from metadata of the digital content item; and generating the transaction right based on a pre-stored rule and digital content item attribute. Because the transaction right is generated based on the attribute of the digital content item, or in other words, the transaction right depends on the attribute of the digital content item, the transaction right generated from digital content items may differ if corresponding attribute associated with digital content items is different. In addition, in addition to metadata, transaction right generation requires only the pre-stored rule, resulting in reduced complexity and cost. As the transaction right also depends on the pre-stored rule, content providers do not need to define the transaction right for each digital content item individually, but can still define the transaction right by setting the pre-stored rule. 2/2
