System architectures that cross organisational boundaries are usually implemented based on Web service technologies due to their inherent interoperability benefits. With increasing flexibility requirements, such as on-demand service provision, a dynamic approach to service architecture focussing on composition at runtime is needed. The possibility of technical faults, but also violations of functional and semantic constraints require a comprehensive notion of context that captures composition-relevant aspects. Context-aware techniques are consequently required to support constraint validation for dynamic service composition. We present techniques to respond to problems occurring during the execution of dynamically composed Web services implemented in WS-BPEL. A notion of context -covering physical and contractual faults and violations -is used to safeguard composed service executions dynamically. Our aim is to present an architectural framework from an application-oriented perspective, addressing practical considerations of a technical framework.

Telemedicine, which is defined as providing healthcare and sharing of medical knowledge over distance using telecommunication means, is a promising approach to improve and enhance the healthcare provisioning process. However, only recently, technology has evolved (i.e. miniaturization of high power mobile devices that can use high bandwidth mobile communication mechanisms) such that feasible advanced telemedicine applications can be developed. Current telemedicine systems offer proprietary solutions that are used in specific disease domains. For the acceptation, rapid development and introduction of novel and advanced telemedicine applications, there is a need for architectural mechanisms that supports developers in rapidly developing such telemedicine applications. The research discussed in this paper, focuses on the development of such mechanisms. * I would like to thank my supervisors M. van Sinderen and A. van Halteren for their contributions to my research and this paper.

Context awareness is a principle used in pervasive services applications to enhance their flexibility and adaptability to changing conditions and dynamic environments. Ontologies provide a suitable framework for context modeling and reasoning. We develop a context model for executable business processes -captured as an ontology for the web services domain. A web service description is attached to a service context profile, which is bound to the context ontology. Context instances can be generated dynamically at services runtime and are bound to context constraint services. Constraint services facilitate both setting up constraint properties and constraint checkers, which determine the dynamic validity of context instances. Data collectors focus on capturing context instances. Runtime integration of both constraint services and data collectors permit the business process to achieve dynamic business goals.
