The e-government platform based on a reused components & mediation

The aim of this paper is to present an architecture based on the reusable components in order to realize an e-government platform. We propose a solution to unify the access to services offered by various administrations, to manage the architectural and functional differences of administrative information systems, to interconnect and allow the exchange between the public administrations. Thus, we propose a solution to permit to each administration to keep its existing on what concerning its information systems, to control its information sources and not to publish them into external.
