摘要： The invention relates to method for deriving a sub-right from a right, the right comprising a plurality of components, each of which specifies an aspect of the right. A component may be, for example, a principal, an action, a resource, and a condition. The invention also relates to a method for integrating a first right with a second right. Furthermore, the invention relates to a method of sharing rights by deriving a sub-right from a right, allowing use of the sub-right, and integrating the sub-right with the right. In addition, the invention relates to a system to support rights sharing by enabling the derivation of a sub-right from a right, the right comprising plural components each of which specifies an aspect of the right, the system comprising a receiving module for receiving a sub-right, the sub-right comprising plural components each of which specifies an aspect of the sub-right, and a confirmation module for confirming that the values of the components of the sub-right can be derived from the values of the corresponding components of the right. The invention further relates to a method for deriving a sub-right from a pool of rights granted by a grantor to a grantee for controlling use of resources within a computing environment, the computing environment having a mechanism for enforcing rights within the environment to control use of resources in accordance with the rights.

摘要： A method and system for managing the state of a protected resource in a system for granting access to a protected resource in accordance with usage rights. The usage rights include at least one state variable indicating a status of an associated protected resource. A message related to the state variable is transmitted from a resource control device to an interface framework. The resource control device is coupled to the resource to control use of the resource by enforcing the usage right. A state controller operative to track the value of the state variable is loaded into the framework and instructed to manipulate the value of the state variable in accordance with said message. For example, the message can be a query of the current value of the state variable.

摘要： Extensible grammar-based rights expression system for processing rights expressions including an interpreter with plug-in subcomponents, a validator, and a framework. In another embodiment, system includes a framework having an extensible architecture with extensibility points for adding extensions to the grammar, and an interpreter, the extensions defining semantics and syntax of new rights expressions. A method for processing rights expressions is also provided having the steps of registering plug-in components, making a programmatic call, finding and invoking appropriate plug-in components, evaluating the request against the grant, and returning an authorization result. In another embodiment, method includes the steps of providing an extensible grammar-based rights expression system having an extensible architecture with an interpreter, evaluating the request against the grant using the interpreter, and returning an authorization result. The method may include the step of adding new extensions to the rights expression system to allow processing of new rights expressions.

摘要： A method and apparatus for managing the transfer of rights associated with items from a rights supplier to a rights consumer. A set of rights is associated with an item and includes meta-rights specifying derivable rights that can be derived therefrom by the rights consumer. The set of rights is transferred, in the form of a license to the item, from the rights supplier to the rights consumer. If it is determined that the rights consumer is entitled to derive the derivable rights specified by the meta-rights, the derivable rights are derived and a license including the derived rights is generated with the rights consumer designated as a principal.
