Towards a two-layered framework for managing web services interaction

Abstract

This paper discusses the use of a framework for analyzing the interactions that arise between Web services engaged in composition. For the sake of achieving better coordination and avoiding conflicts, this framework assigns interactions to two layers known as business logic and support. The business-logic layer comprises control and transactional flows, whereas the support layer comprises exception and message flows. Additional features of this framework include the use of context to oversee interaction progress between Web services and a set of policies to constrain the behavior of these Web services.
