Using dynamic object name in YAML scheme

I want to validate YAML files in Python with my own scheme. A valid YAML shall look like this:

input:
  - name1
split_to:
  windows:
    - split1
  other:
    - split2

While [windows, other] are dynamic, any name shall allowed there (i.e. “solaris”, “mac”, “templeOS”)

I’m using validate from jsonschema like described here: Validating a yaml document in python

Any other module where this works would be also okay.

You’re searching for additionalProperties:

type: object
properties:
  input:
    type: array
    items:
      type: string
  split_to:
    type: object
    additionalProperties:
      type: array
      items:
        type: string
additionalProperties: false

Setting it to false disallows unknown properties in the root mapping. Since JSON Schema is for JSON, keys will always be strings and you can set only the value type for additional properties.
