This paper describes a method for distributed ontology development and its implementation. In addition to the discussion on general distributed development, we especially focus on how to keep the consistency of sub-ontologies as a whole. Its method is based on the management of the dependency between concepts definitions in the sub-ontologies. Aiming at supporting of distributed ontology development comprehensively, we design and implement a prototype system in "Hozo" which has been developed by the authors as a support system for constructing and using ontology.

The Semantic Web, proposed by Tim Berners-Lee, has been paid much attention as the ontology-enabled Web tomorrow. Recently, various areas of research and technology is forming their further expectation with continuous development and the changing definitions. This report tries to figure the concept of ongoing project, which aims at promoting the knowledge-engineering technologies by regarding metamodel management paradigm as the Semantic Web viewpoint.
