Focusing the need of the IWSBO, this paper brings forward the WODOS (WebOriented Distributed Ontology System), which is a model of the Distributed Ontology System in Web environment.The characteristic of the WODOS is that it can store, refer and process the ontology distributively and ensure the con-sistency and uniformity of the ontology in Web environment.展开更多
