WS-PSC monitor: A tool chain for monitoring temporal and timing properties in composite service based on property sequence chart

Abstract

Web service composition is a new paradigm to develop distributed and reactive software-intensive systems. Due to the autonomous attribute of each basic service, validation of composite services must be extended from design time to run-time. In this paper, we describe a novel tool chain called WS-PSC Monitor to monitor temporal and timing properties in composite service based on graphical specification property sequence chart and timed property sequence chart. The tool chain provides a completely graphical front-end which can make software designers do not have to deal with any particular textual and logical formalism. © 2010 Springer-Verlag.
