EDN at least provides date literals, UUID literals, and decimals. It also does not require commas to be littered everywhere. Unfortunately EDN is only really well-supported within Clojure. I'm not sure what is meant by "context problem" for JSON, but keywords and symbols in EDN can be namespaced, so that one can distinguish e.g. :human/name and :computer/name. However, it still requires you to write a schema. And due to lack of support in other languages, protocol buffers seem to be a much better choice.
