Expectation JSON Schemas

Specification

Expectation JSON schemas should conform to the JsonSchema7 interface. We ensure this by validating each schema using the python jsonschema library (e.g. using Draft7Validator.check_schema()).

Metadata Property

Properties on the Expectation schemas represent class instance variable definitions except for one special property: metadata

The metadata property is itself an object containing many properties. The metadata properties are all defined by a const which does not change from one Expectation instance to another.
