If I understand the question correctly, it applies only to old data sets and not to data sets applicable today in the scientific domain. I think the answer is transparency, meaning that certainly there is a need for transparency in the actions taken, in the case of Canada, by the cabinet office in relation to which data sets to open and in which format to open them. So, there are two points.
First of all, open data requires an ecosystem of actors who work together. You have the organization that sets the policy but then you have the other parts of the administration that also produce the data sets and share the data sets that need to be brought on board.
Second, there is the need to be transparent. In order to overcome some of the resistance—and you mentioned some of the negative impressions—there is a need to be transparent about what is going to be done in terms of which data sets will be opened, in which format, at which point, and for use by whom. So there might be scaled-up approaches. Not all governments have taken the approach of getting data out there. For a couple of governments—in the Netherlands and in Denmark, for instance—the approach has been less adventurous, but there's been clarity and transparency about it.
