#source_dataset ⇒ Object

For the purpose of caching, it’s helpful to have the dataset that is actually responsible for creating the model instance since it’s likely that if the instance is updated you’ll want the dataset related to it to be cleaned up. See #recache_source_dataset! for further information.
