Abstract: 【Purpose/significance】As an important part of Chinese culture, the use of modern semantic organization to achieve the or⁃ ganization of massive heterogeneous Chinese traditional opera thematic digital resources is conducive to realizing the excavation and release of the cultural value of Chinese traditional opera.【Method/process】Based on the application of value co-creation theory in the field of cultural heritage, this study comprehensively collects open digital resources provided by various types of subjects, including government departments, enterprises and universities, and proposes the construction scheme of the knowledge graph pattern layer of Chinese traditional operas according to the seven-step knowledge modelling process, and at the same time, the specific pattern layer of the graph is constructed by using the tools of Protégé and Neo4j. At the same time, the specific application demonstration of the schema layer of the atlas was carried out.【Result/conclusion】This study is aimed at fully releasing the cultural value of Chinese tradi⁃ tional opera and music, and proposes a schema layer design scheme and application strategy that includes 11 entity classes, 24 entity subclasses, and 7 major relationship types based on the manual combing of 120 thematic literatures and 40 thematic website contents, in order to support the innovative development of China′s traditional opera and music culture from the perspective of resource organiza⁃ tion. The schema layer design scheme and application strategy are proposed.【Innovation/limitation】This study proposes a domain knowledge graph schema layer construction scheme for Chinese traditional opera information organization scenarios under the perspec⁃ tive of value co-creation, but there is still room for improvement at the level of specific practical details, and the introduction of large language models and other ways to enhance the efficiency of graph construction will be further considered.
