Good OSS Project for REST / Resource Examples

Hi,

I'm pretty new to rails, though not to web development generally. I love the simplicity of the RESTful controller design approach - many small classes with less responsibilities sounds good to me - but I'm struggling to find any rich examples that will answer the questions I have as I try to apply the principles in the real world.

Some good resources I've found have been * railscasts routing episodes: Ruby on Rails Screencasts - RailsCasts * jamis buick's blog: Buckblog: Nesting resources

...but I still feel like I'm thrashing around a bit.

So it strikes me that the best thing would be too root around in someone else's code. Can anyone recommend an open-source rails app which would serve as a guiding light to me on my quest?

thanks, Matt
