  1. 1. 電離層電気伝導度計算を事例とした IUGONET データ解析ソフトウェアによる数値モデルの 取り扱い 小山 幸伸 *1, 新堀 淳樹 *2, 堀 智昭 *3, 能勢 正仁 *1, 田中 良昌 *1 Issues & Solution of upper atmospheric research http://www.iugonet.org / *4 京大・理・地磁気センター , *2 京大生存研 , *3 名古屋大学 STE 研 , *4 極地研 Ideally, the metadata DB system which can deal with arbitrary metadata is the best but • default setting of DSpace is for Dublin Core metadata format, • IUGONET Common metadata format has deeper tree structure than Dublin Core metadata format. The integration analysis by using various kinds of observational data is necessity for investigating the mechanism of long-term variations in the upper atmosphere. However, there are no way to cross-search their DBs which are distributed over many research institutes in Japan. For resolving this inconvenience, we build the Metadata DB in order to cross-search their DBs. Collaboration by using OpenSearch Issues: Global Observation Networks •Observational DBs are distributed. •To find out & collect many kinds of data is difficult. IUGONET provide the analysis software. • Metadata which includes location information (e.g., URI) of observational data is sent to the analysis software via OpenSearch. Combine DBs on metadata level Hurdle of the interdisciplinary study •The analysis software downloads observational data by using the location information. Metadata DB   Search of various observational data at 1 query http://search.iugonet.org/open-search/ Analysis Soft.

Conclusion Customized DSpace-1.7.0 http://search.iugonet.org/iugonet/ Observational Data Link to the Observational Data • 電離層電気伝導度計算、 • ドキュメント、インストーラーを整備後、本プロシージャを公開 予定、 参考文献 Metadata Format & Customization Points We defined the IUGONET common metadata format which is based on the SPASE Data Model [1]. Basically the metadata includes URI of observational data, start & end time of observation, spatial coverage of observation and so forth. [1] Maeda, K., Conductivity and drift in the ionosphere, J.
