Ontology is an essential resource to enhance the performance of information processing system as well as is an intelligent storage area served for management of largescale heterogeneous digital contents resulting. In this paper, we propose the initial steps for reconstructing a significant schema of Vietnamese traditional dances. Most of the typical dances of Vietnamese community are recorded in multimedia format, in raw videos. Accordingly, we concentrated on analyzing and collecting knowledge of the dance experts at art schools in Vietnam to classify and to determine the primary features that would be stored in the ontology. We propose an ontologybased modelling for the cultural heritage domain of Vietnamese traditional dance.
