Architecture and tools for open, interoperable and portable EHRs.

Electronic Health Record (EHR) systems provide the kernel application of health information systems and health networks which should be independent of complexity, localisation constraints, platforms, protocols, etc. Based on shared care information systems' requirements for high level interoperability, a generic component architecture has been introduced. For implementing, running and maintaining acceptable and useable health information systems components, all views of the ISO Reference Model--Open Distributed Processing have to be considered. Following the Model Driven Architecture paradigm, a reference model as well as concept-representing domain models both independent of platforms must be specified, which are combined and harmonised as well as automatically transferred into platform-specific models using appropriate tools.
