Abstract

The evolution of the Internet and Web has led governments to reshape traditional public services and supply the faster, better and more responsive access to public services to citizens called e-Government. E-Government is not only the electronic interactions between citizens and government agencies but also the co-operations among independent government affiliated agencies where different systems exist. These cooperations raise research challenges of heterogeneous interoperating environment in e-Government. This paper will examine the e-Government aspects and then identify the requirements in order to propose a G2G and G2B interoperability architecture based on Service-Oriented Architecture (SOA) approach, the new trend of software architecture and distributed computing technology, along with technical standards, maturity model, and some key actions meant to make the initiative sustainable in the longer term. It is built on top of existing experiences in e-Government Interoperability Frameworks (eGIFs) of some countries across the globe and it addresses some specific peculiarities and needs of developing countries, like DRC.
