Abstract: The construction of the knowledge base of Chinese traditional music resources is in line with the cultural strategies of China to promote national music and prosper the music industry, and it also meets the demands of the joint construction of library resources in the music circle. The construction of " metadata ontology" is the key point, especially the design for the characteristics of Chinese traditional music and the knowledge structure of Chinese traditional musicology. The research is based on the practice of the "Chinese Traditional Music Culture Resource Bank" in the library of the China Conservatory of Music, especially in combination with the characteristics of its " image records" ,to carry out the design of the basic ontology scheme; combined with the characteristics of traditional music culture related to multiple fields, it constructs corresponding categories, relationships and semantic constraints, such as involving music genres, musical instruments, and thesaurus of ethnic groups, and semantic associations with repertoire, musicians, regions, and written documents. This program will benefit traditional music classification research and knowledge retrieval in vertical fields, and has application prospects in music geography and music anthropology community analysis.The construction of the knowledge base of Chinese traditional music resources is in line with the cultural strategies of China to promote national music and prosper the music industry, and it also meets the demands of the joint construction of library resources in the music circle.
