Editing JSON (section)

== Metadata and schema ==
The official [[MIME type]] for JSON text is <code>application/json</code>,<ref>{{cite web|url=https://www.iana.org/assignments/media-types/application/index.html|title=Media Types|work=iana.org|access-date=13 September 2015}}</ref> and most modern implementations have adopted this. Legacy MIME types include <code>text/json</code>, <code>text/x-json</code>, and <code>text/javascript</code>.<ref>{{Cite web |date=2023-01-13 |title=Correct Content-Type Header for JSON |url=https://reqbin.com/req/abghm4zf/json-content-type |access-date=2024-03-23 |website=ReqBin}}</ref>  The standard filename extension is .json.<ref>{{cite journal |url=https://datatracker.ietf.org/doc/html/rfc8259#section-11 |title=11.

''JSON Schema'' specifies a JSON-based format to define the structure of JSON data for validation, documentation, and interaction control. It provides a contract for the JSON data required by a given application and how that data can be modified.<ref>{{cite web|url=https://json-schema.org//|title=JSON Schema and Hyper-Schema|work=json-schema.org|access-date=8 June 2021}}</ref> JSON Schema is based on the concepts from [[XML Schema (W3C)|XML Schema]] (XSD) but is JSON-based. As in XSD, the same serialization/deserialization tools can be used both for the schema and data, and it is self-describing. It is specified in an [[Internet Draft]] at the IETF, with the latest version as of 2024 being "Draft 2020-12".<ref>{{Cite web |title=JSON Schema - Specification Links |url=https://json-schema.org/specification-links |access-date=2024-03-22 |website=json-schema.org}}</ref> There are several validators available for different programming languages,<ref>{{cite web|url=https://json-schema.org/implementations.html|title=JSON Schema Implementations|work=json-schema.org|access-date=8 June 2021 |archive-date=2021-06-16 |archive-url=https://web.archive.org/web/20210616234051/http://json-schema.org/implementations.html |url-status=dead}}</ref> each with varying levels of conformance.

The JSON standard does not support object [[Reference (computer science)|references]], but an [[IETF]] draft standard for JSON-based object references exists.<ref>{{cite journal |last=Zyp |first=Kris |editor-last=Bryan |editor-first=Paul C. |title=JSON Reference: draft-pbryan-zyp-json-ref-03 |website=Internet Engineering Task Force |date=September 16, 2012|url=https://datatracker.ietf.org/doc/html/draft-pbryan-zyp-json-ref-03 }}</ref>
