Service-Oriented Architecture for Seamless and Interoperable Service Delivery

Abstract

The delivery of seamless services is an essential feature of e-government applications. Offering seamless services presents several operational implications; a flexible and interoperable architecture is needed in order to provide some facilities to refer to, invoke and com-bine e-government services in a standard way, within the context of cross-organizational workflows. This chapter presents an e-government architecture (eGovSM) that eases the cooperation among applications of different government agencies in order to supply new added value services. Moreover it promotes reuse of existing systems by integrating governmental legacy applications. The eGovSM (eGovernment Service Marketplace) is a service oriented architecture based on Web Services and XML technology.
