This is a really great project from both the French and German governments. I think state-funded open source solutions to digital platforms is a fantastic opportunity to get away from the big tech walled gardens. Of course, there is always the risk that this becomes unmaintained in the future, but the community at least can take over. But until then, it's a nice platform and a nice contribution to the community.
Those projects could truly be owned by the public and not solely corporations or government. Clearly data is the big thing, and I don't want to have to trust a government or corporation with access to all of it.
In reality, having been part of some of these projects, they often get bogged down by getting all parties and funding organised, in other words, death by committee.
