Abstract: 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.

Key words:  , Bibliographic data, Mapping, Conversion, CNMARC, MARC21, BIBFRAME
