# reservationContainerReference

A unique identifier for the array containing the reservation objects.

```
@NSCopying var reservationContainerReference: INSpeakableString? { get }
```

## Discussion

This property contains an [`INSpeakableString`](/documentation/Intents/INSpeakableString) that serves as an identifier for the list of reservations about which the user requested details. Set the [`vocabularyIdentifier`](/documentation/Intents/INSpeakable/vocabularyIdentifier) property to a string that uniquely identifies the group of reservations within your app and the [`spokenPhrase`](/documentation/Intents/INSpeakable/spokenPhrase) property to a string that makes sense to the user when displayed.
