My understanding is that Joinup is a tool used inside the European Union to create online communities, and that CoHuBiCoL is doing some research into Rules As Code and has created a Joinup Community on the topic that interested people can join.
What they have so far worries me a little. Too much conflating smart contracts with blockchain, too academic, and too willing to conclude in advance that there is a risk of injury to law or comp sci from combining them. But if they are sincere about learning, the data may fix those sorts of issues.
