Simple Obligation and Right Model (SORM) - for the Runtime Management of Electronic Service Contracts

Online purchase and delivery of goods and services requires an electronic contracting process. Formalization of contractual content enables automatic delivery of services and monitoring of the terms and conditions of the contract at service runtime. The Simple Obligation and Right Model (SORM) provides an abstract, domain-independent model of contractual content. Model instances can be interpreted and managed by applications involved in checking contractual entitlements and delivering and supervising a service in compliance with contractual rights and obligations. It captures the main types of rights and obligations and deals with their dynamics during the life-time of a contract.
