Programming Representational State Transfer (REST)
There should be a proper description and documentation of the resources that can
be accessed by using a "gradual unfolding methodology" to expose data for clients. Proper linking to other related resources in every representation to enable clients to drill down for more information should be there.You should know how to use the software to setup a server that can do content negotiation, authentication, authorization, compression, caching, vacuuming and house cleaning. A proper abstractions should be there so the implementation can be carried out in a good way. If there is abstractions then it can survive the storm of change from different implementations and new technologies.
