如何在OpenAPI中拥有自定义数据类型？

Question

我正在尝试创建一个REST API，并有不同的路由到每个端点以返回值，但是它不接受自定义数据类型，例如日期或坐标。我试图创建它，但仍未得到认可。

  Coordinate:
    type: object
    required:
      - longitude
      - latitude
    properties:
      longitude:
        type: number
        description: longitude for coordinate
      latitude:
        type: number
        description: latitude for coordinate

   facilities:
    properties:
     id:
       type: number
       description: facility Id
     name:
       type: string
       description: facility Name
     coordinates: #this gives an error says invalid data type
       type: Coordinate
       description: facility Coordinate
     address:
       type: string
       description: address of facility
     energyConsumption:
       allOf:
       - type: string
       - type: integer
       - type: boolean
       - type: number
       - type: array
       - type: object

我应该像这样进行坐标

{(123,123),{2144123,123444)}
