Abstract
The Interuniversity Upper atmosphere Global Observation NETwork (IUGONET) project is a 6-year research project which started in 2009. The objective of this project is to establish a metadata database of various ground-based observation data covering a wide region from the Sun to the Earth; this will encourage more studies on the mechanisms of long-term variations in the upper atmosphere. For archiving purposes, the metadata database system for cross-searching various data distributed across many universities and institute was developed based on the existing repository software called DSpace as the core component and the Space Physics Archive Search and Extract (SPASE) data model as the metadata format. The IUGONET metadata database is still in operation since it was released in March 2012. The system is continuously examined, tested, and updated to improve its quality. The OpenSearch interface in the IUGONET metadata database allows the user to use external applications easily for exchanging metadata and/or for analyzing data. We conducted self-examination of our product, which was added for planning future directions of the IUGONET project.
Highlights
The Interuniversity Upper atmosphere Global Observation NETwork (IUGONET) project is a 6-year research project which started in 2009
This project has developed two tools: one is a metadata database for crosssearching the atmospheric data distributed across different universities and institutes and the other is an analysis software for visualizing and analyzing data (Tanaka et al 2013)
IUGONET is a challenging approach because it handles a variety of observational projects and related components, for example, instrument, observatory, person, data itself, and so on, in single metadata format and database structure
Summary
The Interuniversity Upper atmosphere Global Observation NETwork (IUGONET) project is a 6-year research project which started in 2009 The objective of this project is to establish a metadata database of various ground-based observation data covering a wide region from the Sun to the Earth; this will encourage more studies on the mechanisms of long-term variations in the upper atmosphere. Problems were faced before each organization released the data to the public, such as lack of human resources for the implementation of the database and the development members' composition mostly inclined toward the specialists in upper atmospheric physics only. There was not enough time to design and implement a metadata database system suitable for natural science
