Option 2) Write your own (little) script (in Ruby, Python, etc.) that exports to JSON or [your data format here]. - Bonus: Share your scripts with the world.
You can see an example in ruby e.g. service.rb [1] at the beerkit repo. It's as simple as:
get '/beer/:key' do |key|
beer = Beer.find_by_key!( key )
json beer.as_json_v2
end
Cheers.
