# metadata

The metadata for the persistent store.

## Declaration

```swift
var metadata: [String : Any]! { get set }
```

## Discussion

Discussion The dictionary must include the store type (NSStoreTypeKey) and UUID (NSStoreUUIDKey). Special Considerations Subclasses must override this property to provide storage and persistence for the store metadata.
