Service Composition (cancelled)

Today's business environments are characterised by an increasing demand for flexibility and interconnectivity. Therefore, new concepts for the development of software platforms like Service Oriented Architecture (SOA) are emerging. An important aspect of SOA is the seamless integration of distributed software systems and thus the composition of services. This tutorial gives a structured overview on service description, discovery, and composition. Issues span from pure technical aspects to goal-oriented, semantically consistent alignment of services and the exchanged data. Approaches for description, modelling, execution and monitoring of composed services are presented. The tutorial facilitates the understanding of benefits and challenges of semantic markup of services focussing on service discovery and automated service composition. Furthermore, it provides insights into the state of the art as well as current research efforts in service description and composition. Finally, the potential of semantic service descriptions is illustrated by a case study based on a real-world scenario taken from the telecommunication industry.

Organization

The tutorial is a half-day activity co-located with ECOWS 2005. It will be held on 9:00 - 12:30 on Monday 14 November 2005 (to be confirmed).

Learning Objectives

The tutorial gives an overview on service composition concepts and motivates the benefits and challenges of semantic markup of services. Additionally, the presented concepts are linked to practical experiences from a case study based on a real-world scenario. Finally, insights into research areas related to service description and composition, including workflow management, ontologies, and artificial intelligence are given.

Target Audience

This tutorial is of interest to researchers, software architects, and students looking for a comprehending insight into state of the art as well as future developments in service description and composition.

Short Bio of presenters

Harald Meyer is a PhD student at the Hasso-Plattner-Institute for IT-Systems Engineering at the University of Potsdam since 2005. His main expertise lies in automated service compostion based on AI planning algorithms, service oriented architectures and software architecture in general. As a part of his Diploma Thesis he developed the service composition component of the Plaengine project. Currently he is working in the Adaptive Services Grid (ASG) project from which the case study is taken.

Hilmar Schuschel is working in the area of business process technology and is specialized in the integration of process planning, process monitoring, and process enactment with focus on service-oriented architectures. Since 2002 he is PhD student at the Hasso-Plattner-Institute for IT-Systems Engineering at the University of Potsdam. He will finish his PhD thesis "Integrated Planning and Enactment of Workflows" by the end of the year. From 2000 to 2001 he worked as a software developer for the Schleupen AG.
