It's a tough one to answer because it is quite new.
I think what we're getting right now is people learning to understand that the resource is available. Especially for public servants, who are just beginning to work in this area, they've got some questions. They know it's useful, but there needs to be some innovation and creativity applied before we're really going to hit that mark.
I think the biggest challenge, and this is the most fundamental thing, is the switch from thinking that as governments we're in an industrial kind of business where we pull all the raw materials out and we shoot the car out the other end. I think we're going to increasingly need public servants who have the ability to think broadly and collaboratively to bring people together on an ongoing kind of basis so that there's energy and movement.
My experience in leading sessions using open data is that it creates a really profoundly focused kind of public discussion, in that you get people who, at certain points, would disagree on a particular issue, but when the data is in front of them that expresses a particular reality, they're much more inclined to engage each other in a really solutions-focused kind of way.
That's just what I've seen in working in sessions.
