   abstract = {Web Services provide a suitable technical foundation for making business
      processes accessible within and across enterprises. The business logic
      encapsulated inside Web Services often resides in already existing
      transactional backend-systems. However, the scope of these systems is normally
      limited to their domain and is not distributed across heterogeneous
      environments.
      
      In this paper, we investigate the impact of the emerging Web Service technology
      on transactional backend-systems: Transactional context needs to propagate from
      activities or even business processes to services they use. Negotiations
      between service requestors and services on context to be propagate can be done
      automatically based on policies attached to the corresponding Web Service
      descriptions. Corresponding standards and mechanisms form the basis of a new
      computing and middleware paradigm: the Business Grid.
      
      Some exemplary research work to be done to actually build the outlined Business
      Grid environment is sketched.},

   abstract = {Web services technology is all about distributed computing. There is no
      fundamentally new basic concept behind this and related technologies. What is
      really new is the reach of Web services and its ubiquitous support by literally
      all major vendors. Most likely, heterogeneity will at the end no longer be an
      obstruc-tion for distributed applications. This will have impact on application
      architectures, middleware, as well as the way in which people will think about
      computing and businesses use computing resources. We sketch these impacts as
      well as some exemplary research work to be done to actually build the outline

   abstract = {The Web services framework is enabling applications from different providers to
      be offered as services that can be used and composed in a loosely-coupled
      manner. Subsequently, the aggregation of services to form composite
      applications and maximize reuse is key. While choreography has received the
      most attention, services often need to be aggregated in a much less constrained
      manner. As a number of different mechanisms emerge to create these
      aggregations, their relation to each other and to prior work is useful when
      deciding how to create an aggregation, as well as in extending the models
      themselves and proposing new ones. In this paper, we discuss Web services
      aggregation by presenting a first-step classification based on the approaches
      taken by the different proposed aggregation techniques. Finally, a number of
      models are presented that are created from combinations of the above.},
