public interface IPDNotFound
extends IPDData
```
Basic interface that is used as a basis for instances where a data object does not exist or cannot be found.
As a general rule, the publish API does not return null when an object cannot be found, for instance when a get method is called. Instead it returns a blank instance for the object.

This blank instance can be easily tested for by calling the #exists() method defined below.
