在当前 MARC 和关联数据共存的复合环境下,研究 MARC 格式中标识符的部署和应用问题,对于简化从MARC到关联数据的转换具有重要意义.以MARC21 和 UNIMARC规范格式中设置的标识符为研究对象,识别和讨论文档网络和数据网络环境交叉融合所带来的新旧概念交替应用问题,具体对MARC 规范格式中的记录控制号和永久记录标识符、本地和远程标识符、规范记录和真实世界对象标识符、RDF URI 和普通网页 URL 等概念和应用进行探讨.结果表明,MARC 规范格式为适应关联数据化发展做出了格式内容上的更新,各类标识符在MARC中承载的功能不同,应著录在不同的字段和子字段以示区分.未来仍需结合编目实践进一步研究标识符著录实施问题,包括URI与相关对象的对应协调,标识符的识别和选择,URI 链接与传统编目工作的权衡等问题.
Research on Development and Application of Linky MARC
In the current hybrid environment where MARC and linked data coexist,it is of great signif-icance to study the deployment and application of identifiers in MARC format to simplify MARC to linked data conversion.Using the identifiers in MARC21 and UNIMARC authority format as research objects,this paper identifies and discusses the problem of alternating application of old and new concepts brought by the hybrid of document network and data network environment.The concept and application of the follow-ing objects in MARC authority are discussed in detail:the local authority record control number and persis-tent record identifier,local and remote identifier,authority record and real-world object identifier,RDF URI and common Web URL.The results show that MARC authority has updated the format and content for the development of linked data.Various identifiers carry different functions in MARC authority,so they should be recorded in different fields and subfields to distinguish.In the future,it still needs further study on the coordination of URI and related objects,the identification and selection of identifiers,the balance between URI link and traditional cataloging work,etc.
