Additional Information: The unique identifier for the dataset is "Application ID". The dataset provides one record per application id and all the existing associated data to that record. In most cases one to many relationships are resolved by providing an aggregate of the values, the most relevant or recent value, or a reduced number of the most relevant values in the dataset. For example if a Water right has more than one Point of Diversion, the dataset includes details of the POD with the most recent updated date. It also provides the number of POD associated to the application ID.
