If you are looking at purely exposing data RESTfully don't go with a heavy weight framework like Django or Rails. I would suggest going with either Sinatra or NodeJS (check out http://expressjs.com http://expressjs.com which is a very light weight, Sinatra like framework for Node). If you already have experience writing JavaScript, NodeJS will make all the more sense, as the language barrier will be removed from the picture.
