When I hear discussions today of free data, as a practitioner and as a business person, I never think there's such a thing as free data. Someone has to pay for it, otherwise it doesn't get collected.
Open data, in our opinion, does not necessarily mean free data. I don't think any of our practitioners and the user community that we speak to will have any issues paying for data at a certain level, and licensing it, because many people can license the same data set and use the same data set over and over again, so the cost per user comes down significantly.
If you want to fly the city of Ottawa with photographs...if you're the only client, it will cost you lots of money; if you're one client of many, it will cost you a lot less. That's our opinion. That's our position on the cost of data.
