Description

This keyword is intended as an alternative to additionalProperties.

Syntax

  • the value of this keyword MUST be a JSON boolean;
  • when this keyword is present, additionalProperties MUST NOT be present.

Applicability

This keyword applies to the validation of JSON Object instances.

Preliminary notes

In the same vein as additionalProperties, properties and others, this keyword is meant to validate the structure of the JSON Object; it has no influence on the validation of object member values.

As such, the validation rules below do not describe the validation of object member values.

Validation rules

If strictProperties is false

Validation always succeeds.

If strictProperties is true

Validation succeeds if and only if the JSON Object:

  • has all properties defined in properties, and
  • has no other properties than the ones defined in properties, patternPropertyGroups and required.
