[目的/意义]ResourceSync是由美国国家标准协会颁布的资源同步框架规范，可用于实现互联网上不同系统之间的资源同步。对该规范的基本原理及其在数字图书馆中的应用场景进行分析，可为ResourceSync在数字图书馆中的实际应用提供借鉴。[方法/过程]从框架结构、同步过程、资源发现机制3个方面分析ResourceSync的基本原理，在此基础上描述ResourceSync在数字图书馆中的3个应用场景，并对实际应用时需要注意的4个问题进行说明。[结果/结论]数字图书馆可以通过ResourceSync支持的3种发现机制来发布或获取资源列表、资源仓库、变化列表、变化仓库，并经过基准同步、增量同步、审校等操作步骤来实现数字图书馆与镜像站点、资源提供者、资源使用者之间的资源同步。

[Purpose/significance] ResourceSync is a framework specification approved by the American National Standards Institute (ANSI), and can be used to achieve resource synchronization of different systems on the Internet. The analysis of its principle and application scenarios in digital libraries can provide references for the practical application in domestic digital libraries. [Method/process] This paper analyzes the basic principle of ResouceSync involving framework structure, synchronization process and resource discovery mechanism. Then it describes three application scenarios, and states four problems that should be noticed. [Result/conclusion] Digital libraries can publish or access resource list, resource dump, change list and change dump through three discovery mechanisms supported by ResourceSync. Resource Synchronization between digital libraries and mirror sites, resource providers or resource users can be achieved through baseline synchronization, incremental synchronization and audit.
