That depends a lot on what a “schema language for JSON” is for you. Generally, this WG has been hesitant to adopt any specimen out of this loosely defined species, but has also been open to letting some flowers bloom. Pete mentioned JCR, which is one of the more expressive proposals. Over at the CBOR WG, we now have a specification approved for the “Concise Data Definition Language”, CDDL, which can describe CBOR data items, and, since the JSON data model is a subset of that of CBOR, JSON data items as well. This has been used to define a number of JSON protocols, e.g., RFC 8007 and RFC 8428 (*). It is not using JSON as its presentation language, but is more concise (**). Since I don’t know your requirements, I’m not sure whether CDDL would be useful for you. Please see https://tools.ietf.org/html/draft-ietf-cbor-cddl — currently in the RFC editor queue.
