A link to the api docs may get you started:  
[http://api.rubyonrails.org/classes/ActiveResource/Base.html#M000827](http://api.rubyonrails.org/classes/ActiveResource/Base.html#M000827)  
Also look at the code generated with scaffold. I simply added a json  
format.

def index  
@sites = Site.find(:all)

```
respond_to do |format|
  format.html # index.html.erb
  format.xml { render :xml => @sites.to_xml }

  format.json { render :json => @sites.to_json }
end

```

end

These are called with the URL:

[http://somesite.org/index.xml](http://somesite.org/index.xml)  
[http://somesite.org/index.json](http://somesite.org/index.json)
