The TranSEHA meeting "Practical Application of Institutional Repository Registration of Cross-Disciplinary Research Data" was held on the third day of the joint research meeting held at the University of Electro-Communications Alliance Center Centennial Hall from Tuesday, September 16th to Friday, September 19th.

1. Introduction to the TranSEHA project
　At this research meeting, Professor Yoshizumi Miyoshi of Center for the Integrated Data Science, on behalf of the members of the Interdisciplinary Database Research and Development Team, gave a presentation titled “Challenges in Registering Interdisciplinary Research Metadata: Initiatives from the Transdisciplinary Network TranSEHA.” The presentation introduced the efforts of the TranSEHA and outlined future plans. This joint research meeting also comprised four other research meetings in the Solar-Terrestrial Physics field: the “STE Phenomenon Report Meeting,” the “MTI Research Meeting,” “Future Mission Considerations for Upper Atmosphere Research Using Ultra-Small Satellites,” and “Understanding and Application of Data Analysis Methods and Tools in Solar-Terrestrial Physics.” Consequently, it provided an opportunity to raise awareness of the TranSEHA activities among numerous researchers and students engaged in diverse fields of research.
2. Introduction to cross-disciplinary data archiving initiatives at other institutions
　Two invited talks were given regarding research data management at other institutions and the utilization of data for scientific achievement, related to the interdisciplinary database creation and data search system development being conducted by the Interdisciplinary Database Research and Development Team. The presentations were “Research Data Management in the Open Science Era” by Dr. Naoto Kai of Osaka University and “Efforts Toward Interdisciplinary Research Data Utilization at the National Institute for Environmental Studies (NIES)” by Dr. Tomoko Shirai of NIES. The Q&A session featured lively discussions on key points for creating interdisciplinary databases and developing data analysis systems as well as the effectiveness of institutional repository registration for advancing open science.
3. Introduction to some examples of the main research at the TranSEHA project
　Associate Professor Fusa Miyake of the Office for the Promotion of Transdisciplinary Network presented “Extreme Solar Events and Ultra-High-Precision Chronology,” while Assistant Professor Hisashi Hayakawa presented “The Severe Solar Storm of February 1956: Current Status, Investigation, and Comparative Analysis of Contemporary Observation Records.” These invited talks presented the latest research findings from investigations, excavations, and comprehensive analyses of severe solar-terrestrial events currently underway at the TranSEHA project. During the Q&A session, there was lively discussion on topics such as methods for rescuing past data and the accuracy of extracted data.

　Furthermore, this research meeting was conducted in a hybrid format, enabling participation both on-site and online. This allowed us to share the contents of the research meeting with many researchers and students who were unable to attend in person.
