A yes. Because things like "integer" totally need to be abstracted away into another schema. Couldn't have given this DSL built-ins for the things that are... you know... built into JSON already.

Also bonus points for the apparent lack of shorthands, turning this language into a verbose word salad. I hope there's at least a line of reasoning that explains why some keys are prefixed with '$' and others aren't.

Great way to turn something as beautifully simple as JSON into something abhorrent.

Hey. You know what is better than JSON at being XML? XML.
