This chapter introduces the goal of ShanghaiGrid and its sub-project E-government on the grid. It first presents the main achievements of the E-government in Shanghai, points out that one of problems of the E-government is how to integrate each government agency’s resources to form cross-agency services for citizens, and argues why grid technique is an ideal way to solve that problem: grid can enable municipal government to integrate its information resources dispersed in different organizations in secure way with open standards and strengthen collaboration and information sharing. Then it gives a conceptual framework of E-government on the grid. Based on the GT3 core services, some core middlewares are developed to support the E-government infrastructure, i.e. workflow, transaction. OGSA-DAI is used to integrate data from different government agencies. The real-name citizen mailbox along with the MyProxy is the basic authentication method used in E-government.
