摘　　要：本文基于对国家保存体系中分布式协作保存网络的需求分析,明确保存网络建设应遵循中心注册管理、独立节点管理、多种类型节点分类、松耦合、异构、网络架构灵活、可扩展、参与机构角色可转换和扩展的设计思路。介绍国家协作保存网络整体框架及节点功能,并对协作保存网络建设和运行的关键问题包括基于注册的管理机制、主动推送的数据提交模式、不同类型节点间的协作模式、唯一持久标识及系统的扩展性进行分析。In this article, based on previous research and requirements analysis, the author clarified the developing principles of national collaborative preservation network, such as central registry, independent node management, multi-typed nodes, loosely coupled, heterogeneous, flexible network architecture, etc. Then, the author described the overall framework of the collaborative network and functions of each type node. It also provided the key issues solutions including the registration-based management mechanism, data exchange model, cooperative mode between different types of nodes, persistent identifier and system scalability.
