日本JPCOAR元模型特点分析与发展趋势研究

Characteristic Analysis and Development Trend of JPCOAR Schema

日本开放获取知识库联盟(JPCOAR)为应对近年来国际形势变化和学术信息发布技术发展、促进日本学术成果的国际流通,开发出了取代junii2的新一代元数据模型,对完善我国机构知识库元数据模型具有较强的借鉴意义。本文梳理了JPCOAR元模型的开发背景、基本原则和特点,并在此基础上分析了日本机构知识库元数据模型未来的发展趋势。研究发现,未来元数据最重要的是正确提供标识符并使其成为易于处理的数据结构,而不是专注于精细化描述。

In response to the recent changes in the international situation and the development of academic information dissemination technology,and in order to promote the international circulation of Japanese academic achievements,JPCOAR has developed a new generation metadata model that replaces junii2.It has strong reference for improving the metadata model of institutional repository of our country.By thorough inspection of the development background,basic principles and characteristics of the JPCOAR Schema,this paper concludes the future development trend of the Japanese Institutional Repository metadata model.The results show that the most important thing about future metadata is to correctly provide the identifier and make it an easy-to-handle data structure,rather than focusing on fine-grained descriptions.
