    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 = {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.},

    abstract = {Graph oriented models are at the core of most business process management
      systems. In recent years, “algebraic” business process modeling languages based
      on different process calculi have been proposed. The semantics of these
      algebraic process languages are quite different, and seemingly incompatible,
      with those of graph oriented approaches. In this paper we study how the BPEL4WS
      exception handling mechanism is used to integrate the algebraic and graph
      process models. Unlike other approaches to exception handling in business
      processes, the BPEL4WS model does not require that the process topology be
      constrained by the exception handling hierarchy, thus allowing both highly
      structured and graph based processes to benefit from it. Based on this
      exception handling model, we explain “dead path elimination” (the runtime
      mechanism by which process termination is ensured) as a form of exception
      processing. The integration of dead path elimination with the exception
      handling mechanism provides the semantic base for the integration of the graph
      and algebraic processes models in BPEL4WS.},
