"So that you can play along at home and test out the code samples in this article, we’ve created a simple web application, based on Ruby on Rails, that implements a RESTful web service. The first step is to download the web application named countries (.DMG, 600 KB). It is based on a simple, database of public domain data containing four fields: A country index, country name, gross domestic product, and two-character country abbreviation.
Our application will perform operations on this database, based on RESTful requests received from a client. Understanding how to implement those requests from your Cocoa and Cocoa Touch applications is our ultimate goal.
When you download the countries web application (.DMG, 600 KB), it can live anywhere on your hard drive. Once it is downloaded, double-click the file REST Article Test Server.zip to create a folder called countries. We won’t need to do anything else to that folder.
Next up, let’s make sure we’ve got Ruby and Rails properly installed."
