Service-oriented computing aims to create complex systems by composing less-complex systems, called services. Since services can be developed independently, the integration of services requires an adaptation mechanism for bridging any incompatibilities. Behavioral adapters aim to adjust the communication between some services to be composed in order to(More)
Currently, communication protocols for medical devices are being developed for the IEEE 1073.2 standard. The protocol description in its draft remote control package consists of a collection of intended behaviors in terms of MSCs. We have contributed to actually constructing the protocol, ranging from determining an hMSC for these MSCs, via synthesizing(More)
As systems become more service oriented and processes increasingly cross organizational boundaries, interaction becomes more important. New technologies support the development of such systems. However, the paradigm shift towards service orientation, requires a fundamentally different way of looking at processes. This survey aims to provide some(More)
Soundness is one of the well-studied properties of processes; it denotes that a final state can be reached from every state that is reachable from the initial state. Soundness-preserving refinements are important for enabling the compositional design of systems. In this paper we concentrate on refinements of service compositions. We model service(More)
Process mining techniques can be used to effectively discover process models from logs with example behaviour. Cross-correlating a discovered model with information in the log can be used to improve the underlying process. However, existing process discovery techniques have two important drawbacks. The produced models tend to be large and complex,(More)
The accordance pre-order describes whether a service can safely be replaced by another service. That is, all partners for the original service should be partners for the new service. Partners for a service interact with the service in such a way that always a certain common goal can be reached. We relate the accordance pre-order to the pre-orders known from(More)
MSC is a visual formalism for specifying the behavior of systems. To obtain implementations for individual processes, the MSC choice construction poses fundamental problems. The best-studied cause is non-local choice, which e.g. is unavoidable in systems with autonomous processes. In this paper we characterize two additional problematic classes of choice(More)
Behavioral adapters are a way to establish proper interaction between services that have been developed independently. We present a novel approach for specifying such adapters, based on domain-specific transformation rules that reflect the elementary operations that adapters can perform. We show how complex adapters that adhere to these rules can be(More)
We study the composition and substitution of services from a theoretical perspective. An important notion is the operating guideline of a service y, which is defined as the set of services x such that the result of connecting x and y has a certain desired property. We define several related notions and derive results for them in a general context, thus(More)
