Sure.
The comment I was going to make on this is that first of all it's important that you have attribution: who is accountable for curating a particular dataset? That's very key here.
The second thing I would say is that it's very important to have an agreed feedback loop whereby, if you choose to crowdsource the accuracy of the data and you invite third parties to participate in it, you have a feedback loop that enables them to do it effectively, so that people see that the data gets updated within that authority—the authority of source of that data—and that the more accurate data is then reflected on a timely basis.
If you have that feedback loop, I think you then give people confidence that this is a real and a sustainable thing and that the quality of the data is improving over time. It's not something you can do as a one-off or a “let's try it and see”; I think you have to have that feedback loop and sustainability effort on top of it.
