The accurate data comes from the source. The source is managed by the people who own and maintain the data. For us, three things have worked: political sponsorship, administrative leadership, and community engagement.
I've been in Ottawa many times this year, and as a Canadian I'm embarrassed by the state we are in compared to other countries. When I'm there I'm always tweeting at people to say we need to do something. The sad thing is that the last time I was there for GTEC I talked about open government, because it's part of open data, and I was told by a number of staff that they're not allowed to talk about open government, they can only talk about open data.
So there needs to be some heart-to-heart discussion somewhere, and there needs to be the political sponsorship, the administrative leadership, and community engagement.
I was very excited with the invitation from the clerk last week. The work you are doing encourages me, but like anything there need to be some outcomes and some direction. I think it's possible; you just need that.
