HATEOAS (Hypermedia as the engine of application state) is an essential but often overlooked / ignored constraint of the REST architectural style. Its importance is not that significant if you’re going to define some APIs for one-time use, i.e., the benefits will only gradually reveal over time. So I draft a simple case study of a sample online order management service to show why adopting HATEOAS is so important for minimizing maintenance cost and ensure backward compatibility.

“Restful User Experience”
It all started the other day when I was trying to explain the difference between RPC & REST to colleagues. I used “dumb phone” vs. iPhone to illustrate my points, which was well received. Then with more ideas popping into my head, I decided to visualize them all and share with others.
Some statements in the slides are arguable, e.g., I love the Pianist application, truly. But I just couldn’t imagine typing on the screen all day 
Anyway I deem the content should be very helpful for better understanding of REST as well as UX by changing perspectives.
BTW: I am an iPhone lover, but not iPhone user, yet. So some observations about iPhone might not be 100% correct. And I hope to touch deep into iPhone OS developer experience soon.
