Since the 1980s, The Korean Social Science Data Archive (KOSSDA) has been the leading research data management organization for Korea’s social science data collection. In 2015, the KOSSDA became a part of the Seoul National University (SNU) research community and found a home within the Asia Center. In 2022 SNU decided to make KOSSDA an independent research organization of the College of Social Science. KOSSDA decided to analyze and evaluate the current KOSSDA service models to prepare for newly expanded research and service opportunities. A small group of researchers conducted usability analyses on KOSSDA data collection, the KOSSDA data education program, the KOSSDA website, and data donors. In this presentation, presenters will share the findings of these usability analyses and discuss the distinctiveness of Korea’s research data management services and data sharing patterns.
