The data center of our institute distributes solid earth science data obtained by the Ocean Hemisphere Project (OHP) network through the website of Pacific 21. We have developed Java-based software "GDSClient", which enables us to collect not only the data of the OHP network but also those distributed from other data centers by means of the web service technology. It is possible to request the data controlling parameters such as data centers, observatories, a data period, and other auxiliary detailed parameters. It is unnecessary to know differences between data centers with preparing a WSDL (Web Services Description Language) file, in which information of user interface is described in XML format. The latest GDSClients are released from the website of Pacific 21.
