Since the proposal in 2013, Data Jacket has been introduced at universities and companies both in Japan and abroad and achieved many results. The Data Jacket Promotion Working Group was launched in February 2017, and Data Jacket has been developed as a standard technology at Data Trading Alliance (DTA) in February 2019. The seminar series has lectures and workshops on how to use Data Jackets in the data market and the real businesses as standardized technology. We are looking forward to your participation. See you soon in the Market of Data.
