In my opinion, this is a really bad title. Something called "CKAN" was released, according to someone named "okfn". That doesn't tell me anything, if I'm not already familiar with either.
It seems to be about "open knowledge" (CKAN = Comprehensive Knowledge Archive Network), but I had to check to find out.
It's "debian for data" i.e. a centralised repository of free data with some housekeeping and rules of thumb to help the individual databases be used together.
