the issue with JSON schemas is that there is no stable language to write 
them in. there were and are a couple of proposals, but there isn't the 
one language do rule them all such as DTD or XSD for XML.

the reason is that parts of the JSON community don't like the idea of a 
schema language at all. there is a lingering perma-thread on the IETF 
JSON list, and because of the heated debates, i think nobody ever had 
the energy to really follow through with a proposal and define and 
standardize a schema language.

that doesn't mean that there aren't scenarios where schemas might be 
useful. just don't be surprised to get passionate reactions when you 
bring up the idea of schemas and a schema language in JSON-land.

cheers,

dret.
