Acts as api
https://github.com/fabrik42/acts as api
makes creating XML/JSON responses in Rails 3 easy and fun
It provides a simple interface to determine the representation of your model data, that should be rendered in your API responses.
In addition to Rails it theoretically can be used with any ruby app and any database (__ActiveRecord__ and __Mongoid__ are supported out of the box) as it only has few dependencies.
The lib is _very_ fast in generating your responses and battle tested in production with platforms like Diaspora or flinc.
