摘 要:尝试在CNMARC字段与BIBFRAME 2.0类及属性之间建立映射关系,以此改变CNMARC存在的语义关系缺失问题,最终实现CNMARC书目数据的关联式发布。以BIBFRAME官网发布的BIBFRAME 2.0模型、词汇以及MARC21向BIBFRAME 2.0转换工具为基础,通过元数据映射及转化方法,尝试在CNMARC字段与BIBFRAME 2.0类及属性之间建立映射,再以CNMARC实体记录为例来构建CNMARC的BIBFRAME化模型。BIBFRAME 2.0词汇以MARC21的字段为基础而建立,故可以参考MARC21的BIBFRAME化转换来实现CNMARC相关数据的BIBFRAME化转换。但由于MARC21与CNMARC间差异性的存在,故在具体转换过程中,存在某些字段无法直接进行转换的情况,需增设必要的类及属性来完成转换。This paper attempts to establish a mapping between CNMARC fields and the class and property of BIBFRAME 2.0, so as to address the lack of semantic relations of CNMARC and to finally realize the linking and opening of CNMARC bibliographic data. Based on the vocabulary and the model of BIBFRAME 2.0 published on the website of BIBFRAME and the conversion tool from MARC21 to BIBFRAME, the mapping between CNMARC fields and BIBFRAME 2.0 class and attribute is attempted by means of metadata mapping and conversion, and then the BIBFRAME model of CNMARC is constructed by taking a CNMARC record as an example. Based on the conversion between MARC21 and BIBFRAME, the conversion between most fields of CNMARC and BIBFRAME can be realized. Meanwhile the vocabulary of BIBFRAME 2.0 is built on the basis of MARC21 fields, so in the process of the conversion, there are some fields of CNMARC that can not be converted directly, making it necessary to add some classes and properties to complete the conversion.
