Preparation of geographic metadata and development of geographic data clearinghouses take a very important role to promote dissemination of Geographic data. We would like to introduce GSI's activity to develop the clearinghouse, according with ISO23950 and Japan Metadata Profile ( JMP ) for the first time in Japan. ISO23950 is an international standard concerned with information search and retrieval protocol. Using this protocol, users can query simultaneously with respect to plural physically distributed clearinghouse nodes.
