Specifying a WS-ECA Framework for Ubiquitous Web Services in Object-Process Methodology

Abstract

The Web Services-Event-Condition-Action (WS-ECA) framework is designed to enable the heterogeneous communication devices in Ubiquitous Computing Environments to achieve inter-operability via event-driven coordination. Object-Process Methodology (OPM) is an integrated modeling method that unifies the function, structure and behavior of a system. This paper presents specifying a WS-ECA framework for ubiquitous web services in OPM. In addition, we propose a dynamic conflict detection and resolution method in which dynamic conflicts are detected by examining the post-conditions of services being triggered and are resolved by acquiring user priority, service priority, and user’s service preference.
