                             ECOWS 2005
              Third European Conference on Web Services
                http://wscc.info/ecows2005/research/

                 Vaxjo, Sweden, 14-16 November 2005

                 *** NEW DEADLINE: 30 June 2005 ***

Sponsored by IEEE Computer Society, Technical Committee on Services
Computing (approval pending).

Scope:

The design of distributed applications and users' expectations for
software evolution have changed dramatically in the last 15 years. An
important milestone was set when distributed object environments (e.g.,
CORBA) made it possible to program distributed applications as if
remote objects were local. This gave birth to a thriving middleware
market and popularized the use of open APIs in the software industry.
This approach led to object-oriented software components, whereby a
group of objects that collectively fulfill a given task provide a
single interface to remote applications; examples include CCM and J2EE.

Over a decade of experience has taught the community (researchers and
practitioners alike) that distributed object computing has inherent
problems, because of the tight coupling that is requires between
distant systems. First, guaranteeing interoperability and openness
among all objects and components in a distributed application is
difficult when these objects are developed by competing commercial
entities. Software vendors prefer to segment markets, because niche
markets are more lucrative than commodity markets. Second, most
customers need to integrate large application chunks (as opposed to
fine-grained objects) written by different vendors, so having
object-level interoperability is often unnecessary in practice.

The success encountered by the Web has convinced most of the community
that tightly coupled software systems are only good for niche markets,
whereas loosely coupled software systems can be more flexible, more
adaptive and often more appropriate in practice. Loose coupling makes
it easier for a given system to interact with other systems (be they
legacy or not) that share very little with it. 

At the crossing of distributed computing and loosely coupled systems lies
service-oriented computing, which appears to many as the next important
step in distributed computing. When applications adopt service-oriented
architectures, they can evolve during their lifespans more easily and
better adapt to changing or unpredictable environments. When properly
implemented, services can be discovered and invoked dynamically using
non-proprietary mechanisms, while each service can still be implemented
in a black-box manner. This is important from a business perspective:
there is no need for customers to "choose their sides" anymore. Each
service can be implemented using any technology, independently of the
others. What matters is that everybody agrees on the integration
technology, and there is a consensus about this in today's middleware
market: customers want to use Web technologies, notably XML.

ECOWS 2005 will cover all aspects of Web Services, which constitute the
main technology available to date for implementing service-oriented
architectures and computing. The main objectives of this conference are
to facilitate exchanges between researchers and practitioners and foster
future collaborations in Europe and beyond. Topics of interest to the
Research Track include, but are not limited to, the following:

  - Modeling of Web Services
  - Design of Web Services
