I originally had something like this, but removed because I was specifically trying not to create new resources.

```yml
# Represents a temporal window of a Dataset
DatasetWindow: !Extends_InformationResource
    # Beginning and End of data window
    time_window: !TemporalBounds
    # ID of the dataset which the time window applies.  Yes, storing an ID here.
    dataset_id: ""

# Defines each Dataset Window for a Site DataProduct
    #@ContentType=DatasetWindow
    dataset_windows: [] A list of DatasetWindow objects
```
