Integrating the semantics of events, processes and tasks across requirements engineering layers.

Today, software should be more flexible, adaptable and more cost effective than ever before. The power of event-based systems lies in the decoupling of sender and recipient which results in highly-flexible, adaptable and loosely-coupled systems. The potential of the event-based architectural style has been recognized by academia and industry, leading to a large variety of products. However, the absence of the event-based architectural style in requirements engineering significantly hampers the implementation of these systems. Often a paradigm shift will occur which makes the automatic translation of event-agnostic platform independent models to event-based platform specific models almost impossible. The aim of this project is the development of an event-based requirements engineering methodology which supports the specification, development and verification of event-based systems. More specifically, the project strives for the development of the event-based style in requirements engineering with a formally defined semantics of events. The event concept is clearly positioned with respect to and is related to existing concepts for modelling dynamic aspects of a system. A major goal is to keep the complexity of the modeling method at an acceptable level. Furthermore, ensuring a smooth transition from requirements to an implementation architecture will be an important validation criterion for the research results.
