Read custom tags

[VedavyasBhatJupiter]

I have custom tags on some Schema objects. I can't find it in the object, though. Is it possible?

components:
  schemas:
    User
      properties:
        userId:
          type: string
          x-custom-tag-1: someValue
          x-custom-tag-2: someOtherValue

It absolutely is; those are called "extensions" and you can read the above ones like so:

dorthu@travel-dev:~/source/openapi3$ cat example.yaml 
openapi: "3.1.0"
info:
paths:
components:
  schemas:
    User:
      properties:
        userId:
          type: string
          x-custom-tag-1: someValue
          x-custom-tag-2: someOtherValue
dorthu@travel-dev:~/source/openapi3$ ipython

In [3]: with open("example.yaml") as f:
   ...:     spec = OpenAPI(safe_load(f.read()))
   ...: 

In [4]: spec.components.schemas['User'].properties['userId'].extensions['custom-tag-1']
Out[4]: 'someValue'
