Swagger supports associative arrays/hashmaps/dictionaries where keys are strings. A dictionary is defined by using an object schema with the additionalProperties keyword specifying the value type of key/value pairs. The key type is not mentioned because keys are always strings.

    type: object
    additionalProperties:
      type: integer
    example:
      apples: 5
      oranges: 7
