Interoperable SOA-based architecture for e-government portal

An effective e-government platform provides greater access to government services among citizens, businesses, and tourists. However, most e-government portals are not integrated as each government agency has its own portal. This may cause confusion and becomes a cumbersome task among stakeholders. This paper proposes a one-stop e-government architecture that integrates one-stop portal, e-government service application, and e-government service provider. The architecture provides seamless interoperability of e-government services among different government agencies. This work exploits various Web technologies and service oriented architecture approaches such as Web portal, portlet, service component architecture, Web services, and BPEL. Finally, this work presents the proof-of-concept of the proposed architecture and a case study in an e-government service environment.
