Service integration has the purpose of
providing the final user with a single
unified service, hiding the distribution
and heterogeneity of the services
provided by the autonomous providers.
Generally, service integration
approaches have focused more on process
modelling and execution aspects than on
data integration, while the latter is
often the most crucial determiner of
successful integration in practice.
Through the use of context, a new
generation of Web services (i.e.,
context-aware Web services) is expected
to arise for the benefit of coping with
the dynamic nature of the Internet. For
instance, the best service provider in
terms of quality guarantees and cost
metrics would differ from
time-to-time. A composite-service
provider must therefore regularly change
the services invoked to provide the best
service to his customers. The task of
identifying the best service to invoke
is the biggest challenge to overcome and
necessitates techniques for detecting
data and functionality changes in a
service, methods for assessing the
quality of the service, computing the
cost of invocation etc.
Although the combination of context
awareness and Web service composition
sounds appealing, injecting context into
adaptive service integration and
management raises a number of
significant challenges, which have not
been widely recognized or addressed
by the Web services community. Some of
How to build a model of change:
data, process and environment?
How, when and where to track the
provenance of data and meta-data?
How to define and use effective and
practical metrics to manage adaptation:
how to compare ability of different
services to adapt? How to compare
What is the role of context and how
to get the right one?
objective of CSSSIA 2008 is to provide a
forum for researchers and practitioners
to exchange new ideas, developments, and
experiences on the key technical
challenges for deployment of
context-enabled, adaptive Web services
and integrated applications. Discussions
will focus on where the state of the art
is and where the challenges lie,
and what practices are needed to enable
and sustain a bright future.
