Data Space Technology International Testbed: An Overview
n Background► The distributed systems required to build a data spaces are huge systems.
► For individual companies and individuals (companies, universities, research
institutes, students, engineers...) , there have been great difficulties in testing these.
► Even if you say, "I want to touch the data space right now," you cannot touch it.

n Activities► Build an open testbed for data space technologies.
u The test environment is built in the computer system environment of the University ofTokyo.
u The test environment is positioned as an experimental environment that can be used freely.
u Using the test environment, learn how to use, implement, and manage and operate thedata space system
u R&D of technologies related to data space infrastructure and data linkage infrastructureu R&D of interoperability between various data space infrastructure and data linkage
infrastructure related technologies
u Once the development of DATA-EX is completed (currently in progress), we will put a newcomponent of DATA-EX into operation► Formation of a "technical community" for data space technology
u Publication of online magazines
u Holding training courses and hands-on workshops
u Collaboration with overseas data space technology communities
u In the future, we want to establish academic society for data spaces.
