摘要
科技信息资源共享服务平台由资源汇交系统、资源加工处理系统、资源目录服务系统和日志系统4个子系统构成。该平台体系的建设采用混合式的P2P体系结构。这种体系结构是用一台中央服务器来存储各节点资源的元数据信息,而各个资源节点服务器则负责存储科技资源数据。这样的混合式P2P体系结构可以更好地管理元数据,也能够支持进一步的资源查询检索。
System resource sharing service platform is constituted by four subsystems, i.e. resources remitted by ＇the system, resource processing systems, resources, directory services system and log system. This paper discusses the program which uses the P2P hybrid architecture, this architecture with a central server stores the resources of each node meta- data information, while each resource node server is responsible for storing data on scientific and technological resources. This hybrid P2P architecture can be better management of metadata, can also support further resource query retrieval.
