Level 1

Resources are exposed, but you still have an HTTP method. If you are at Level 0, then changing your web service to return a resource will take you from level 0 to level 1. You still have one HTTP method, but when your method is invoked, your service will pass back a resource:

    Request: 
    POST 
    diet/ate 
    Response 
    diet/ate/12789 
    Request: 
    POST 
    diet/ate 
    Response: 
    diet/ate/99000 

There is one endpoint diet/ate still, it returns many resources.
