高校图书馆持久标识符应用研究

Exploring the Application of Persistent Identifiers in University Libraries

为了实现高校图书馆数字资源的持久标识,促进系统间互操作性的增强,本文对持久标识符进行了广泛深入调研,对当前应用最为广泛的4种持久标识符的原理和国内外应用情况进行了梳理,从费用、使用量、互操作、标识符与元数据四个方面对其做了全面地比较分析。结合北京大学图书馆的实际情况,介绍了持久标识符在开放研究数据平台、机构知识库、系统间互操作上的应用。

In order to identify the digital resources persistently in university libraries and to promote the interoperability between the systems, this paper has made an extensive research on persistent identifiers and its applications. Firstly, the paper introduced the four most widely used persistent identifiers and their applications at home and abroad, then made a comprehensive comparison and analysis from the aspects of cost, usage, interoperability, identifier and metadata. Finally, based on the practice of Peking University Library, this paper introduced the application of persistent identifier in the open research data platform, in- stitutional repository and interoperability between the systems.
