Great to see. 

There is some confusion about the license however.
On the blog post and at http://data.kirjastot.fi/data.html I see CC0
But at   http://thedatahub.org/dataset/helmet I see the license text "CC Share-Alike" with a link
to http://opendefinition.org/licenses/cc-by-sa/

What are the implications of wrapping CC0 in CC-BY-SA? 

Was this a deliberate change of license? 

If deliberate, where exactly is the "BY" requirement defined?  
(Who is the "creator" of this dataset, and who is licensing it: the finnish library or OKFN?)

Or is it just a mistake?
