A lot of applications these days title themselves RESTful. But how much REST is needed to be RESTful?
There is much discussion these days about HATEOAS (Hypermedia as the engine of application state) so it gets time to clearly say what HATEOAS actually means.
As it seems, Marc and Paul (the leaders of JAX-RS / Jersey) really have understood what OpenSource really means: Communicate with the community, understand their needs and thoughts, accept their ideas. I would wish that more project leaders would assimilate this open mind and welcoming kind of leadership.
