The IWS (Intelligent Web Services) is the result of the development of the network computing model.This paper discusses that it's necessity for the ontology to be brought into the IWS and introduces the vision of the I-WSBO (IWS Based on the Ontology). 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.
