Support unevaluatedProperties OpenAPI 3.1

[minardus]

unevaluatedProperties is in 3.1 spec, it is the same as additionalProperties, but it can see through $refs.

Example:

Request:
  required:
    - id
  properties:
    id:
      description: Id
      type: integer
  type: object
  unevaluatedProperties: false
ExtendedRequest:
  required:
      - extra_id
  allOf:
        -
          $ref: '#/components/schemas/Request'
        -
          properties:
            extra_id:
              description: 'Extra ID'
              type: integer
    unevaluatedProperties: false

Request can only accept id ExtendedRequest can only accept id AND extra_id

It is now not checked by the validator, so I can send extra parameters like 'extra_parameter' and it's still valid. If I use additionalProperties: false, it will read Request first, and then it will immediately give error extra_id is not allowed

This is maybe because 3.1 is not fully supported yet? Because Attribute/Annotations should also support it then

If I use additionalProperties instead I get this

Keyword validation failed: Data has additional properties (extra_id) which are not allowed Field

And as I read it, this is not supported by additionalProperties, but is supported by unevaluatedProperties

Also the problem is described here

https://github.com/json-schema-org/json-schema-spec/issues/661

The only solution is to 'unroll' the properties into ExtendedRequest, so no inheritance takes place and I can use additionalProperties. Maybe the code could support generating it like that? That would also solve my issue for now. So not reffing but copying the properties.

I have found out I can bypass it by using Traits (I was extending). This will make a copy instead of using allOf: - $ref

Have you tried and verified that unevaluatedProperties is supported by tools like swagger-ui? Just asking as I do not have time to track things at that level.
