@<1719162259181146112:profile|ShakySnake40> the data is still present in the parent and it won't be uploaded again. Also, when you pull a child dataset you are also pulling the dataset's parent data. dataset.id is a string that uniquely identifies each dataset in the system. In my example, you are using the ID to reference a dataset which would be a parent of the newly created dataset (that is, after getting the dataset via Dataset.get )
