The JavaScript Object Notation Data Interchange Format
RFC 8259, “The JavaScript Object Notation Data Interchange Format”, is an Internet Standard document published in December 2017 by T. Bray. It obsoletes RFC 7159. The canonical text is published by the RFC Editor.
Abstract
JavaScript Object Notation (JSON) is a lightweight, text-based, language-independent data interchange format. It was derived from the ECMAScript Programming Language Standard. JSON defines a small set of formatting rules for the portable representation of structured data.
This document removes inconsistencies with other specifications of JSON, repairs specification errors, and offers experience-based interoperability guidance.
What “Internet Standard” means
A mature, widely-implemented specification that has completed the full IETF standards process — the highest maturity level on the standards track.
