Development of applications for open data for Japanese laws and regulations


  • Makoto Nakamura Niigata Institute of Technology


Japan's e-legislation system, e-LAWS, began operating in 2016. This allows the drafting and publication of laws and regulations to be done electronically, whereas previously they were done on paper. One of the most important technologies supporting e-LAWS is the Japanese Legal Standard XML Schema, which is tailored to Japanese laws and regulations. The launch of e-LAWS has made it possible to share Japanese laws and regulations as open data. Our purpose in this study is to provide Akoma Ntoso applications for Japanese law data. As a result of our project in progress, we have confirmed that some applications work with the Japanese law data. This is expected to facilitate not only the use of Japanese law data by everyone, but also sharing with legal data around the world.
