Our approach was to work with municipal governments in a variety of individual cities.
In Edmonton for example, we would work with the office of the city clerk. In Edmonton they have quite a robust open data initiative of their own. We asked them, if they would, to help us contact local users—local companies, the post-secondary institutions, civil society organizations, and government representatives as well. We created the widest possible invitation list we could and sent it out and invited them all to come for a day.
