AB: One of the problems for all of the Earth-scale observations is the circulation of the observation data. In the Solar-Terrestrial Physics (STP), variety types of spacecraft and ground-based observations have been done, and, as a result, large amounts of data have been stored and still being stored. These observations have been usually conducted by different organizations, thus the observation data are stored, managed and publicized independently. The present study is devoted to develop a global system, the Solar-Terrestrial data Analysis and Reference System (STARS), for easy accesses to these independently managed observation data seamlessly, without paying attention to where they are provided. For the use of such distributed databases, it is preferable to make full use of the Internet. We first constructed a meta-database of the STP observation data. This database manages the directory information of data files, including data site information and data file information. It also manages users_f affiliation and attributes since, in the STP, data access are often restricted to the mission members only for a certain period after the beginning of the mission. The number of meta-data record is now more than 2,000,000. It contains the information of the ISAS/JAXA spacecraft observation data files, the CDAWeb (GSFC/NASA) data files, magnetograms and geo-magnetic indices data files, the polar region observation data files by NIPR, STE laboratory and NICT in Japan, and other observation data files. We then constructed a network application, by which everyone is able to make use of the meta-data through the Internet. The application searches, visualizes and analyzes the observation data. The STARS application communicates with the meta-database using the XML Web Service (hereafter Web Service). The Web Service provides with so-called "loose connection", thus seems to be most adequate for the use of the STP data over the Internet. Using the STARS application, uses on the Internet are able to get data file information, download them and make plots. The XML is used not only for the Web Service, but for the exchanges of data plots, personal discoveries of special events, and knowledge of data analyses between the users through the Internet. This system will, therefore, show us a new paradigm of the STP data analyses.
