The report you refer to, Dr. Bennett, is indeed a thoughtful piece, and I think it is one that is good for people to reflect on. One of the workers at our institute was involved in creating it, and I believe it has some good elements to it that are specific for Canada as well.
I'm not aware of a government yet that has fully regulated these areas, so I don't know that there are best examples. I do know of some examples that seem not to work. They seem to create a lot of unintended consequences because they're very specifically referring to a scale regulation rather than a product regulation, and I think that's difficult.
Unfortunately, I think the European Union is moving towards that aspect of it as well, but that's still under discussion. I think one of the frameworks that are necessary is being managed by what's called Technical Committee 229 of the ISO, in which they are trying to start with a definition framework and a terminology framework and nomenclature, so people know what they're talking about, and that's almost a prerequisite for being able to do things well.
