# itemReference

A unique reference for the reservation.

```
@NSCopying var itemReference: INSpeakableString { get }
```

## Discussion

Provide information that identifies this specific reservation. The [`vocabularyIdentifier`](/documentation/Intents/INSpeakable/vocabularyIdentifier) should be specific enough that your app can use it to retrieve and display this reservation’s info later. The [`spokenPhrase`](/documentation/Intents/INSpeakable/spokenPhrase) should describe the event to the user. For example, a restaurant reservation might use a phrase like `“Table for 2 at McNeil’s on February 11”` or `“7pm at McNeil’s”`. For a multi-part reservation, such as a round-trip ticket, provide an `itemReference` that is specific to this portion of the overall reservation.
