    摘要: A system and method for processing a rights expression for association with an item for use in a system for controlling use of the item in accordance with the rights expression. A rights expression is specified in a conventional manner in an original format. An intermediate format of the rights expression is generated based on at least one of syntax information and semantics information associated with the original format. The rights expression specifies a manner of use of said item for enforcement on a device. The intermediate format can be converted to a device specific format or a simplified format for resource constrained devices to permit rights enforcement on various devices.

    摘要: A system and method for distribution of digital works in a tree-like structure of devices. A hierarchical right may include a first usage right governing a use for the digital work and a first delegation right governing distribution of the digital work to child nodes of the tree-like structure. A second usage right and/or a second delegation right may be generated based on the hierarchical right, the second usage right governing a use for the digital work and the second delegation right governing distribution of the digital work to child nodes of a first child node of the tree-like structure. The second usage right and/or the second delegation right may be assigned to a version of the digital work, and the second usage right and/or the second delegation right and the version of the digital work may be forwarded to the first child node.

    摘要: Flags are used to mark portions of content in a digital work to permit marking or demarcation of portions of the document. The demarcated portions can be handled in various ways. For example, different usage rights can be applied to demarcated portions, the demarcated portionis can be culled for use as a summary, or the like. The flags can be used to demarcate portions of content that has been downloaded to keep track of payment and download status and thus add flexibility to electronic distribution of content. A flag usage rights element can be attached to limit and control access to flags in a desired manner.
