> JSON Feed files must be served using the same MIME type — application/json — that’s used whenever JSON is served.
So then it's JSON, and I'll treat it as any other JSON: a document that is either an object or an array, that can include other objects or arrays, as well as numbers and strings. Property names doesn't matter, nor do order of properties or array items, or whatever values are contained therein.
Please don't try to overload media types like this. Atom isn't served as `application/xml` precisely because it isn't XML; it's served as `application/atom+xml`. For a media type that is JSON-like but isn't JSON, you may wish to look at `application/hal+json`; incidentally there's also `application/hal+xml` for the XML variant.
Or as someone else rightly suggested, consider just using JSON-LD.
