System and methods for manipulating rights expressions for use in connection with a rights management system include one or more tokenized templates. Each tokenized template includes one or more rights expression language statements and one or more tokens associated with at least one of the rights expression language statements. Further, the tokens can be place holders for data items or rights expression elements. The system further includes a license template module that creates the tokenized templates, and a license instance creation module that replaces at least one of the tokens in one or more selected license templates with one or more of the data items or rights expression elements to generate a license instance. Additionally, the system includes a license instance analysis module having sub-modules for validating and interpreting license instances, and a data parsing module for extracting data from created license instances.

Systems and methods for creating, manipulating and processing rights and contract expressions using tokenized templates

The publishing system and method automates at least some portion of a publishing process. The system publishes content using metadata, rights templates and/or specifications, publishing profiles and business rules.

Method and system for automatically publishing content

Usage rights for a digital work are established prior to creation of the corresponding content. The rights can be associated with the content after the content is created. A content creation, such as a video recorder or a still camera, device can store labels of the rights and can associate usage rights with content in real time as the content is created.

Method and apparatus for establishing usage rights for digital content to be created in the future

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.

Extensible rights expression processing system

Method, system, and computer readable medium for automatically publishing content

Legality expressions are systematically pre-processed, organized, and stored to achieve faster real-time response, improved predictability, and increased reliability for queries against a large volume of legality expressions. Exponential improvements in both the time to locate the set of legality expressions matching specified search criteria and the processing costs of evaluating the request against the matching legality expressions are achieved using the disclosed systems, devices, and methods. The systems, devices, and methods are unique to the optimization of legality expression processing, but they can also enable the use of other optimization techniques for processing large amounts of data.
