Nowadays, we can access several meteorological databases through the Internet. They are, however, heterogeneous in access methods, data formats, available items etc., so that clients applications are generally tightly linked to particular databases. This causes inefficiency in usage of data resources and development of client applications. To solve this issue, we developed a data broker named MetBroker, which provides client applications consistent accesses to such heterogeneous databases. The structure of the original MetBroker is extremely inflexible particularly because the definition of weather items is not structured and all the translating procedures are statically implemented. In this study, we suggest a method to solve the inflexibility by making MetBroker able to handle semantic heterogeneity with Web ontology.
