Contract and rights management - and thusproperty rights protection - has gained increasingimportance as a quality standard in brokerage andelectronic commerce environments. Contract andrights management provides information on thelegal relationships associated with digital assets, aswell as intellectual property rights protection andthe enforcement of rights. However, many brokerageand e-commerce platforms currently in operationwere not originally designed to support contract andrights management. In this context, we identify openissues in digital contract and rights managementand present a framework design to resolve theseissues. This framework uses standardized XML-basedrights expression languages, reuses anexisting role-based access control component forrights enforcement, and is extensible with value-addedservice components for rights management.The reference project for our work is a(heterogeneous) P2P network of interactingbrokerage platforms for learning resources.
