ASG - Techniques of Adaptivity

Authors: Harald Meyer, Dominik Kuropka, and Peter Tröger

Published in: Dagstuhl Seminar Proceedings, Volume 7061, Autonomous and Adaptive Web Services (2007)


Abstract
The introduction of service-orientation leads to significant improvements regarding flexibility in the choice of business partners and IT-systems. This requires an increased adaptability of enterprise software landscapes as the environment is more dynamic than the ones in traditional approaches. In this paper we present different types of adaptation scenarios for service compositions and their implementation in a service provision platform. Based on experiences from the Adaptive Services Grid (ASG) project, we show how dynamic adaptation strategies are able to support an automated selection, composition and binding of services during run-time.

Composing Web-service-like abstract state machines (ASM)

Authors: Andreas Friesen and Lemcke Jens

Published in: Dagstuhl Seminar Proceedings, Volume 7061, Autonomous and Adaptive Web Services (2007)


Abstract
The presentation provides an overview on semi-automatic design of Collaborative Business Processes for B2B/EAI integration in the EU project FUSION. The introduced Enterprise Application Integration Ontology and a mediator-based run-time architecture for CBPs integrating heterogeneous web services enabled enterprise systems build the corner stones of the FUSION solution. The functionality and the building blocks of the Collaborative Business Process Designer are discussed in detail. The talk provides then an example demonstrating initial ideas for generating an executable collaborative business process out of a CBP template automatically.

Role of semantics in Autonomic and Adaptive Web Services & Processes

Authors: Amit P. Sheth

Published in: Dagstuhl Seminar Proceedings, Volume 7061, Autonomous and Adaptive Web Services (2007)


Abstract
The emergence of Service Oriented Architectures (SOA) has created a new paradigm of loosely coupled distributed systems. In the METEOR-S project, we have studied the comprehensive role of semantics in all stages of the life cycle of service and process-- including annotation, publication, discovery, interoperability/data mediation, and composition. In 2002-2003, we had offered a broad framework of semantics consisting of four types:1) Data semantics, 2) Functional semantics, 3) Non-Functional semantics and 4) Execution semantics. This talk describes the need for the four types of semantics, its standards-based support through WSDL-S/SAWSDL, and the need for such semantic representation to dynamic and adaptive SOA. We also briefly review the proposal for Adaptive Web Processes introduced earlier in a ICSOC 2005 vision talk.

Towards Analyzing Declarative Workflows

Authors: Dirk Fahland

Published in: Dagstuhl Seminar Proceedings, Volume 7061, Autonomous and Adaptive Web Services (2007)


Abstract
Enacting tasks in a workflow cannot always follow a pre-defined process model. In application domains like disaster management workflows are partially specified and circumstances of their enactment change. There exist various approaches for formal workflow models that are effective in such situations, like declarative specifications instead of operational models for formalizing flexible workflow process. These powerful models leave a gap to existing techniques in the domain of workflow modeling, workflow analysis, and workflow management. In this paper we bridge this gap with a compositional mechanism for translating declarative workflow models to operational workflow models. The mechanism is of a general nature and we reveal its principles as we provide an exemplary definition for translating DecSerFlow models based on LTL to Petri nets. We then demonstrate its use in analyzing and refining declarative models.

05462 Service-Oriented Computing: A Research Roadmap

Authors: Michael P. Papazoglou, Paolo Traverso, Schahram Dustdar, Frank Leymann, and Bernd J. Krämer

Published in: Dagstuhl Seminar Proceedings, Volume 5462, Service Oriented Computing (SOC) (2006)


Abstract
This document presents a Services Research Roadmap that launches four pivotal, inherently related, research themes to Service-Oriented Computing (SOC): service foundations, service composition, service management and monitoring and service-oriented engineering. Each theme is introduced briefly from a technology, state of the art and scientific challenges standpoint. From the technology standpoint a comprehensive review of state of the art, standards, and current research activities in each key area is provided. From the state of the art the major open problems and bottlenecks to progress are identified. During the during seminar each core theme was initially introduced by a leading expert in the field who described the state of the art and highlighting open problems and important research topics for the SOC community to work on in the future. These experts were then asked to coordinate parallel workgroups that were entrusted with an in-depth analysis of the research opportunities and needs in the respective theme. The findings presented in this summary report build on the advice of those panels of experts from industry and academia who participated in this Dagstuhl Seminar and met at other occasions during the past three years, e.g., at the International Conference on Service Oriented Computing (ICSOC, see www.icsoc.org). These experts represent many disciplines including distributed computing, database and information systems, software engineering, computer architectures and middleware and knowledge representation.
