The $schema property within a JSON document signifies that the document is a JSON Schema, it can also indicate the version of the JSON Schema standard used. The values for the supported standards are as follows
- https://json-schema.org/draft/2020-12/schema
- https://json-schema.org/draft/2019-09/schema
- http://json-schema.org/draft-07/schema#
- http://json-schema.org/draft-06/schema#
- http://json-schema.org/draft-04/schema#
If the value http://json-schema.org/schema# is used, it indicates that it is a JSON Schema, but is not specific about the version used to author it.
As not all version of the JSON Schema standard are backwardly compatible, it is recommended that you set the $schema property to a specific JSON Schema standard, so any applications processing it will deal with it correctly.
