1. Figure out the data set
2. Split the data set into resources.
   For each kind of resource:
3. Name the resources with URIs.
4. Expose a subset of the uniform interface.
5. Design the representation(s) accepted from the client.
6. Design the representation(s) served to the client.
7. Integrate this resource into eisting resources, using hypermedia links and forms.
8. Consider the typical course of events: what's supposed to happen?
9. Consider error conditions: what might go wrong?
