JSON schema not required

Overview. JSON Schema validation asserts constraints on the structure of instance data . An instance location that satisfies all asserted constraints is then annotated with any keywords that contain non-assertion information, such as descriptive metadata and usage hints.

JSON is case-sensitive . SQL is case-insensitive, but names in SQL code are implicitly uppercase.

JSON Schema Validation: The JSON Schema Validation specification is the document that defines the valid ways to define validation constraints . This document also defines a set of keywords that can be used to specify validations for a JSON API.

The enum keyword is used to restrict a value to a fixed set of values . It must be an array with at least one element, where each element is unique.
