That's a good question. I don't have a good answer for you in the short term. Can you directly attribute a savings to the release of a given data set? That's going to be a very tough challenge.
What I think you are going to be able to see, over time--and I think again we're very early days--is certain economies that have access to more information about their economy and the communities they serve, and because they have more access to information, they are going to become more efficient and they are going to grow faster.
Data is like the plankton of our ecosystem, of the economy in the 21 century. So if you starve that system of plankton or another system has more of it, they're going to thrive more. I think there will be some very simple examples we'll be able to look at.
There might be some specific ones. When I look at Vancouver, and I look at some of the stuff that's been done, there's a local architecture firm, Bing Thom Architects, that has taken open data from the city's portal and has written a number of reports. It's looked at what rising sea levels will do to the city of Vancouver and the costs it will have on building infrastructure. Those reports are very powerful for city hall staff and for councillors. I don't know how many free consulting services we've received from Bing Thom Architects so far, but I've got to believe it's somewhere north of $100,000 to $200,000. So that's real value that's generated for the city and for the citizens.
Can I quantify that en masse? It would be a very difficult challenge.
