@jens I've read the description provided and found it very useful and it all makes sense. I do not have enough experience/knowledge to validate it but I see its usefulness in some fields. However I'm not sure yet if the Gaia-X project will include working groups that will go into that "level of details". At present we are dealing with the high level infrastructure components and protocols for managing compliant exchanges in data spaces. @NGIZero @onepict
