Abstract(in English) With the conventional GIS system, we can know where people or objects are but not know what they are doing or what situation they are in. Any context aware service does not operate properly in that environment. To produce Ubiquitous LBS system, we are going to create Semantic Geospatial Web system. Almost all the researches and applications of these systems are based on centralized server system. It is inconvenient because many metadata will be transmitted with P2P-like method in the Ubiquitous environment, e.g. mobile ad hoc network. To solve this problem, we propose a distributed method of metadata using location information and hash values of metadata. Using routing tables, queries are efficiently transmitted to proper terminals.
