This is an area where you would really benefit from hearing from experts in the field of open government. Policy experts can explain it to you much better than I can.
Essentially, when you publish data it comes with conditions. In Canada we have crown copyright. It's very different from the U.S., where the information does not belong to the crown. When they decided to publish their data sets it was a very different environment. The U.K. and Australia are very interesting jurisdictions to look at for that purpose.
When information is being disclosed in other jurisdictions, they provide provisos on it. You can use it for this purpose, but it's no longer the property of the government. You have a certain licence to use it, and various conditions apply to it.
These have to be developed. This is part of the complexity of moving in that direction. That's why I'm saying it's not just a question of publishing information. It requires looking at these types of issues--copyright, official languages, privacy concerns, national security concerns--and how we protect the integrity of the data.
I urge the committee to speak to public policy experts like David Eaves, who can explain all of that much better than I ever could, because I'm not an expert in the actual manipulation of the data itself. You really need a technology expert and an expert in open government who uses these types of formats.
