Tools for Composite Web Services: A Short Overview

摘要

Web services technologies enable flexible and dynamic inter-operation of autonomous software and information systems. A central challenge is the development of modeling techniques and tools for eanbling the (semi-)automatic composition and analysis of these services, taking into account their semantic and behavioral properties. This paper presents an overview of the fundamental assumptions and concepts underlying current work on service composition, and provides a sampling of key results in the area. It also provides a brief tour of several composition models including semantic web services, the "Roman" model, and the Mealy/conversation model.
