摘　　要：对国际上主要分布式数字资源保存网络进行调查分析,涉及基于LOCKSS、网格技术等多种技术架构的保存网络系统。这些分布式数字资源保存技术架构及模型,基本都遵循MetaArchive发布的《分布式数字保存建设指南》提出的基本原则。在介绍中科院文献情报中心长期保存项目(DPS)的分布式系统架构基础上,提出建设分布式数字资源保存系统需要重点考虑的问题:唯一标识符、开放的系统架构、节点分工协作、多复本间的校验通讯等。In this paper, investigation and analysis have been done about the distributed digital preservation network involved systems that based on LOCKSS, grid technology, etc. , which have basically followed the fun- damental principles put forward by A Guide to Distributed Digital Preservation released by MetaArchive. Based on the introduction of the distributed DPS architecture of the Document and Information Center of Chinese Acad- emy of Sciences, some important considerations for building distributed digital preservation system have been dis- cussed, which include unique identifier, open system architecture, collaboration of multiple nodes, verification and communication among multiple copies, and so on. 7 figs. 1 tab. 18 refs.
