A competitive data economy requires the smooth exchange of data. This is why MISSION KI, an initiative of the German National Academy of Science and Engineering and the Federal Ministry for Digital and Transport Affairs, commissioned five of the most renowned German institutes in the field of data standardization to develop an FDO infrastructure for the cross-sector networking of data spaces in January 2024. Two months later, the research consortium, of which the GWDG is a member, is now presenting a demonstrator of the FDO infrastructure for the first time at the International FAIR Digital Objects Implementation Summit, March 20-21, 2024, Berlin.
