Services Specification, Composition, and Enactment (Prof. Dr. M. Weske)

 An important challenge in Services-based systems engineering is the composition of processes consisting of individual services as well as their controlled enactment.

While manual composition of services might be promising in specific usage scenarios, semi-automated or even automated service composition is more appropriate in highly dynamic environments, such as those found in today's business scenarios.

In order to facilitate this advanced type of service composition, existing concepts and languages for service specification have to be enriched with more expressive, semantics-based concepts. Engineering methods are required to develop feasible services composition methods.

Once service compositions are determined, the respective processes need to be enacted. Based on known concepts from workflow technology and requirements for services-based processes, new concepts and software architectures need to be developed.

In particular, proposals in the following research areas are invited:

 * Semantically enriched specification of services

 * Automatic and semi-automatic services composition

 * Engineering of process aspects in services-based systems

 * Software architectures for adaptive service enactment
