ServiceClass specification

  • The ServiceClass message defines the amenities and comfort level of a vehicle journey.

  • ServiceClassType is an enum within ServiceClass that specifies the service class, including FIRST_CLASS, SECOND_CLASS, SINGLE_CLASS, and BUSINESS_CLASS.

  • Specific service classes, like NON_RESERVED_SECOND_CLASS, RESERVED_SECOND_CLASS, RESERVED_GREEN_CAR_CLASS, and RESERVED_GRAN_CLASS, are available for the Japan market.

  • The JSON sample illustrates how to represent the service class type, with "type" set to "FIRST_CLASS" in this example.

  • When using protocol buffer libraries, it's recommended to include SERVICE_CLASS_TYPE_UNSPECIFIED = 0 within the ServiceClass.ServiceClassType enum.

When adding new classes to ServiceClassType, ensure they adhere to the following guidelines:

  • Local Standards: The classes should represent the local standard of service classes for the intended mode of transport in the target market.
  • Hardware-Focused: They should represent the physical attributes and amenities of the vehicle (the "hardware") rather than a partner's specific pricing structure or fare conditions (e.g. refundability, flexibility).
  • Reusability: Different partners should be able to use the same classes when providing prices for the same type of vehicle. This avoids proliferation of partner-specific enums and ensures consistency.
