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.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=INPROC-2005-126&engl=0} }

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.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=INPROC-2005-125&engl=0} }

especially by the fact that portType and operation names are hard-coded in the

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

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.}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=INPROC-2005-121&engl=0} }

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).}, url = {http://www2.informatik.uni-stuttgart.de/cgi-bin/NCSTRL/NCSTRL_view.pl?id=INPROC-2005-120&engl=0} }
