基于Atom的数字图书馆资源描述框架

A Lightweight Resource Description Framework of DL Based on Atom Syndication Format

文章从元数据互操作的角度出发，提出一个适用于数字图书馆领域的资源概念模型，采用Atom连锁格式描述，希望能够利用Atom的内建特性简化数字图书馆系统之间的数据集成工作，既保证原始数据的完整性，又可以实现完全无损失的元数据互操作。文章从对元数据互操作技术的概述开始，介绍了Atom的基本特性，阐明选择Atom描述资源的理由。在分析Atom在数字图书馆领域的应用基础上，提出基于Atom的数字图书馆资源描述框架，并给出期刊文献的描述样例，同时给出一个基于Atom机制构建的数字图书馆资源网络，指出重构资源网络框架将面临的风险及规避方法。文章结尾指出下一步的主要研究内容。

In the view of metadata intempembility, this paper provides a resource description fi＇amework in the field of digital library. The DL-RDF/Atom is based on the Atom Syndication Format in order to use the built-in features to simplify the procedure of data integration, both to ensure the integrity of the original data and can achieve metadata interoperability without loss of data. First, this paper outlines the technologies of metadata interoperability, introduces the basic characteristics of Atom and explains the reason of choosing Atom. After the analysis of Atom applications in the field of DL, this paper describes the Digital Library Resource Description Framework based on Atom, gives a journal literature sample, and analyzes a DL resource network based on Atom mechanism. This paper points out the risk of DL-RDF/ Atom and methods to minimize the risk. Finally, this paper lists the contents of the future reseach.
