   abstract = {This document presents a Services Research Roadmap that launches four pivotal, inherently related, research themes to Service-Oriented Computing (SOC): service foundations, service composition, service management and monitoring and service-oriented engineering. Each theme is introduced briefly from a technology, state of the art and scientific challenges standpoint. From the technology standpoint a comprehensive review of state of the art, standards, and current research activities in each key area is provided. From the state of the art the major open problems and bottlenecks to progress are identified. During the during seminar each core theme was initially introduced by a leading expert in the field who described the state of the art and highlighting open problems and important research topics for the SOC community to work on in the future. These experts were then asked to coordinate parallel workgroups that were entrusted with an in-depth analysis of the research opportunities and needs in the respective theme. The findings presented in this summary report build on the advice of those panels of experts from industry and academia who participated in this Dagstuhl Seminar and met at other occasions during the past three years, e.g., at the International Conference on Service Oriented Computing (ICSOC, see www.icsoc.org). These experts represent many disciplines including distributed computing, database and information systems, software engineering, computer architectures and middleware and knowledge representation.},

   abstract = {WS-coordination and WS-CF provide support for distributed activities that require coordination in an environment of Web services. Both specifications are generic coordination frameworks, not specific for any application. Despite their generic character, up to now only transactional protocols have been defined, which leverage these coordination frameworks. In this work we map a distributed activity, that it is not related to transactions, onto the coordination model underlying WS-coordination and WS-CF. Consequently we identify the necessary characteristics of a distributed activity that leverages the coordination frameworks of WS-coordination and WS-CF. We also examine limits of these coordination frameworks and suggest additional mechanisms where support for coordination in particular use cases is not sufficient. In contrast to coordinating distributed transactions, additional problems could arise when other types of activities are subject to coordination. These problems are studied, classified and reviewed in conjunction with the architectural differences of WS-coordination and WS-CF.},

   abstract = {The flexibility and reusability of Web Service flows (WS-flows) are limited especially by the fact that portType and operation names are hard-coded in the process definition. In this paper we argue that through parameterization and substitution WS-flows flexibility can be improved, while reusability is enhanced. We introduce a meta-model extension to enable run time evaluation of parameter values and thus discard the need to predict any possible partner service types during process modeling. The extension enables also run time changes in portType values. We show how the approach can be mapped to BPEL. We discuss prototypical implementation for the extended functionality and present conclusions and ideas for future work.},

   abstract = {The existing Web service flow (WS-flow) technologies enable both static and dynamic binding of participating Web services (WSs) on the process model level. Adaptability on per-instance basis is not sufficiently supported and therefore must be addressed to improve process flexibility upon changes in the environment. Ad-hoc process instance changes can be enabled by swapping participating WS instances, by modifying port types of the partners to be invoked, and by changing process logic. In this work, we address the problem of dynamic binding of WSs to WS-flow instances at run time, i.e. the ability to exchange a WS instance participating in a WS-flow instance with an alternative one. The problem is additionally complicated by the fact that the execution of a process depends on its deployment. We describe the ``find and bind'' mechanism, and we show its representation as a BPEL extension. We discuss the benefits that could be gained and the disadvantages it brings in. The mechanism extends and improves the existing process technologies. It facilitates a precisely controlled policy-based selection of WSs at run time and also provides for process instance repair, while maintaining simplicity. We also discuss a prototypical implementation of the presented functionality.},

   abstract = {Business process management (BPM) is the approach to manage the execution of IT-supported business operations from a business expert's view rather than from a technical perspective. However, the degree of mechanization in BPM is still very limited, creating inertia in the necessary evolution and dynamics of business processes, and BPM does not provide a truly unified view on the process space of an organization. We trace back the problem of mechanization of BPM to an ontological one, i.e. the lack of machine-accessible semantics, and argue that the modeling constructs of semantic Web services frameworks, especially WSMO, are a natural fit to creating such a representation. As a consequence, we propose to combine SWS and BPM and create one consolidated technology, which we call semantic business process management (SBPM).},

This ensures that a choreography once specified can be deployed and executed in every workflow system within a Grid environment. It is likely that the Business Process Execution Language (BPEL) will have the corresponding broad support in the industry. In order to become first class citizens in the Grid, choreographies have to comply with the resource framework. We therefore suggest steps to make BPEL compliant with the resource framework. As a result, features of BPEL such as extended transactions will be available in a Grid environment.},
