Json Data Types Pdf Json Data Type Json schema has a set of keywords to describe and optionally validate non json data stored inside json strings. since it would be difficult to write validators for many media types, json schema validators are not required to validate the contents of json strings based on these keywords. This document proposes a format, called json type definition (jtd), for describing the shape of javascript object notation (json) messages. its main goals are to enable code generation from schemas as well as portable validation with standardized error indicators.
