Abstract: In view of low efficiency of ontology storage and query based on relational database or other databases, BaseX as an XML database is proposed to store ontoloy, besides, the architecture of it is also designed. Based on the research of BaseX storage structure and its interface, ontology storage is implemented. OWL ontology query is implemented by using the BaseX query interface and Xquery language, and ontology query extension and reasoning are implemented on the basis of inference rules library. The experiments compare the ontology storage and query method put forward in this paper with the classic method based on the relational database, which verify the method in this paper has more efficient storage and query performance, along with the ability of ontology query reasoning.

Key words: ontology storage, ontology query, BaseX, eXtensible Markup Language（XML） database
