Great @oeoeaio, thank you for this detailed answer!
Thanks you for those ideas and explanations, our visions are for sure aligned 
This is also connected to this discussion Product supply chain tracability and the contact I had with Provenance (ping @johba) … but anyway, as you see, we need to be able to fund that before going further, but that’s something we could emphasize in the funding applications we will make in France
I will come back to you when we are on it to ask you maybe for an estimation., I guess it’s a pretty big job…
For the report point, thanks for the info as well, and budget (one day), so if the hub we mentioned need that we know how much that will cost if they need that report, so again, I’ll come back to you when we have the budget for that
Ping @Selmo for info in your future exchanges with Jean-Marc
