How-to: Validate Enum Values (JSON Schema)

Use enum to restrict allowed values.

1. Define the input

inputs:
  mode:
    type: string

2. Add JSON Schema hint

hints:
  - class: eoap:JSONSchemaHint
    json_schema:
      type: object
      required: [mode]
      properties:
        mode:
          type: string
          enum: [fast, strict]

3. Validate with sample values

Valid:

mode: "strict"

Run:

assertions-mate workflow.cwl --inputs inputs-valid.yaml
