数字资源的持久标识符互操作参考模型构想

Conception of Persistent Identifier Interoperability Reference Model for Digital Resources

认为国外持久标识符的研究存在研究对象过于具体、应用范围有限等不足,很大程度上是由于没有在一个整体框架指导下来开展研究所致,鉴于此,提出一个持久标识符互操作参考模型,模型主要组成部分是持久标识符域,包括登记机构、内容提供商以及解析器等,对三类数字资源实体(数字对象、作者、机构)和持久标识符之间的关系进行标准化,便于管理、表示和呈现数字资源,并可为实现正确的互操作解决方案和交换奠定基础。最后,指出本模型在安全性、可伸缩性等方面有待进一步完善和改良。

This paper investigates related projects of persistent identifier overseas. It finds some limitations, such as too specific research objects, limited applying scope, which are largely due to lack of a general framework. Thus, it pro- poses a persistent identifier interoperability reference model which is mainly composed of persistent identifier domains in- cluding registration agency, content provider and resolver. The model makes relationships between entities （digital ob- jects, authors, institutions） and their persistent identifiers standardized, which is convenient to manage express and pres- ent digital resources, to lay ground for correct interoperability solution and exchange. Lastly, it points out the model＇ s needs of refinement and improvement in security, scalability, etc.
