I really like this. In general, a well-supported non-crappy schema language for modern data exchange formats is long overdue (e.g. JSON Schema is horribly un-human-friendly). The fact that they aim higher and allow for a much more detailed set of validations is great, IMO.

I hope that this becomes a success and gets implementations in many programming languages.

For "human-friendliness" (eg. hand-edited configs), I'm all in with YAML. AFAIC, JSON is strictly for machine to machine data transmission.

While I think the idea is neat, a data language should not include processing logic. It's a wash where the constraints get specified, and in my experience, a single point of implementation is far more maintainable.

I think I'm a bit confused, is Q the actual schema or a validator of the schema? I can also validate a JSON document using JavaScript and respond with a true or false based on whether it meets certain criteria. So I think that there's something amiss with your statement above, specifically that "JSON Schema is horribly un-human-friendly". Doesn't Q take JSON and let the user know if it's correct or incorrect? WOuldn't JavaScript, or any other language at that, do the same?

JSON Schema refers to http://json-schema.org/

I don't personally understand what is so "un-human-friendly" about it. It is easy to use and understand in my opinion.

I know what JSON is :)

JSON Schema != JSON.

have you seen orderly?

For data exchange, what is wrong with using an ASN1 specified, BER encoded file? Genuine question...

The binary encodings are cumbersome and difficult to perfect.

Isn't it simply a matter of delegating it to a library -- the encoding and decoding I mean? I have had occasion to use Java and Python libraries for this and faced no problems.
