Towards an approach for weaving preferences into web services operation

Existing approaches on Web services privacy dominate solutions from a users’ perspective, giving little consideration to the preferences of Web service providers. The integration of service providers’ preferences into Web services’ operations is discussed in this paper. A Web service provider indicates peer Web services that it could interact with as well as the data that they could exchange with. We focus on Privacy and (trust) Partnership preferences based on which, we develop a Specification for Privacy and Partnership Preferences (S3P). This specification suggests a list of exceptional actions to deploy at run-time when these preferences are not met. An integration model of these preferences into Web services design is illustrated throughout a running scenario, and an implementation framework proves the S3P concept.Zakaria Maamar, Quan Z.

Towards a two-layered framework for managing web services interaction

© Copyright 2007 IEEE – All Rights ReservedThis 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.Maamar, Z., Benslimane, D. and Sheng, Q.Z
