RestfulX

RestfulX is a framework that brings the design principles and productivity of Rails to Adobe Flex and AIR development and makes integration with RESTful Web Services as simple as possible. If you want to use Ruby on Rails, Merb, Sinatra, CouchDB or Google App Engine and you want a UI that puts the word Rich into Rich Internet Applications give RestfulX a spin. It only takes 5 minutes to get started. Instead of WSDL, SOAP or other complex specifications you'll find a few common conventions that help you to abstract your application from repetitive CRUD code and switch/synchronize between various data providers with minimal effort.

• Adobe Flex/AIR Developers. If you know your data-binding inside out and you can run circles around component life-cycle RestfulX can help you focus on making your application stand out instead of figuring out what to do with the data that comes in JSON and XML or how to use SQLite.
• Ruby and Python Developers looking to use Adobe Flex or AIR technologies to create rich internet experiences. Even if you have little or no knowledge of ActionScript 3.0 you should be able to start creating functional Flex and AIR applications in no time.
