For example, consider GeoDID representing a collection of satellite imagery. We should be able to specify a sub-collection, or even item, that defines a spatial and temporal query in the GeoDID itself. That way, a user could store a single GeoDID that specifies a single image, clipped to a particular area, extracted from the GeoDID Collection. The user would not need to store that clipped image, but only the GeoDID with query parameters - they would still have the confidence that the GeoDID would resolve to the same clipped image permanently.
