In your other comment you call this a ’hack and a PR thing’ and it is exactly that: a neat hack to draw attention to the fact that the government is now publishing this data-set as free data.

I think it’s great the government publishes this free data (given as it is was probably collected using tax money), and I also think it’s great they do a project to attract attention to this: the more people know about this data, the more people can use it, and the better the tax money has been spent.

Plus, I imagine the Danish blog post provides good starting points for anyone wishing to use this data in similar ways.
