eGovCloud:一种基于云服务的电子政务框架

EGovCloud:A cloud-service based e-government framework

针对电子政务建设过程中涉及的异构资源即时共享和跨部门业务协同等核心问题,提出一种基于云服务的电子政务框架eGovCloud,其核心思想是通过"虚拟资源中心"实现资源物理上的分布存储和逻辑上的集中管理,并建立政务领域元数据规范作为统一的语义基础设施,进而支持跨部门异构信息资源的共享和统一管理,以此为基础进一步提出支持跨部门业务协同的"政务虚拟组织"。探讨了eGovCloud体系结构以及涉及的关键技术,并展示了其在构建电子政务系统中的应用。

In order to facilitate on demand resource sharing and cross-organizational collaboration in E-Government systems,the paper proposes a cloud-service based framework（EGovCloud）,which utilizes the virtual resource repository to realize resource physically distributed storage and logically centralized management.E-Government metadata specifications are constructed as a unified semantic infrastructure and therefore support cross-organizational heterogeneous resource sharing and management.We explore the architecture of EGovCloud and the key technologies involved,and demonstrate the applications in constructing E-Government systems.
