RDR has become an essential academic infrastructure in an atmosphere that facilitates the openness of research output granted by public research funds. This study aims to understand operational status of 152 Asian data repositories on re3data and cluster repositories into four groups according to their operational status. In addition, identify the main subject areas of RDRs in Asian countries and try to understand what topic correlations exist between data archived in Asian countries.
This study extracts metadata from re3data and analyzes it in various ways to grasp the current status of research data repositories in Asian countries. The author clusters the repositories into four groups using hierarchical cluster analysis according to the level of operation. In addition, for identifying the main subject areas of RDRs in Asian countries, extracted the keywords of the subject field assigned to the each repository, and Pathfinder Network (PFNET) analysis is performed.
About 70 per cent of the Asian-country repositories are those where licenses or policies are declared but not granted permanent identifiers and international-level certification. As a result of the subject domain analysis, eight clusters are formed centering on life sciences and natural sciences.
The research output in developing countries, especially non-English-speaking countries, tends not to be smoothly circulated in the international community due to the immaturity of the open-access culture, as well as linguistic and technical problems. This study has value, in that it investigates the status of Asian countries’ research data management and global distribution infrastructure in global open-science trends.
