I haven't heard it described like that, but in a sense I guess. At Nature (where it was developed) we use it to decouple our front and back ends. So when we work on a feature we agree on a JSON structure beforehand and work in parallel. It also gives us the ability to work in exactly the same way on the front-end no matter which back-end system is producing the JSON. This is awesome if you're a company that has applications written in quite a few languages
