JSON Schema is a JSON language for describing the data structures of other JSON documents.
JSON Schema is referenced by more than 10 IETF RFCs, hundreds of IETF Internet-Drafts,
and in the specifications of many other organizations such as 3GPP, W3C, HR Open Standards,
OpenBanking UK, OpenAPI, ETSI, C2PA and more. JSON Schema is widely used in many commercial
and open source offerings.

However, there is no stable IETF specification for JSON Schema. JSON Schema is described
in at least 5 IETF Internet-Drafts but has never been published as an RFC. The goal of
this working group is to produce a stable, reference specification of JSON Schema as an
IETF Proposed Standard. This stable specification will contain only features and
mechanisms in JSON Schema that are in known use, and the working group may remove features
and mechanisms it is (a) confident are not in use and (b) are likely not to be used in
the future. To achieve this goal, this working group also has the following scope:

* Documenting, mitigating, or fixing any security concerns with JSON Schema.
* Registering values into existing IANA registries, such as a media-type for JSON Schema documents.
* Creating new IANA registries specific to JSON Schema.

This working group will not produce any other language for describing JSON data structures.
The working group may recharter to broaden the group's scope of work only after completing the
group's initial milestone.
