Only dataset modifiers can perform a delete action on a hierarchy of columns of a dataset.
You can only delete virtual elements. If you do not know the ID of your virtual elements, the current structure of the hierarchy can be retrieved as a tree via the get call.
Hierarchies are not associated/dissociated, they are directly targeted towards a specific column upon update or delete.
Virtual vs value elements
There are two types of hierarchy elements:
Values: elements that have an 'id' that matches with an existing 'data' value or that will match with a future data value in the column.
Virtuals: elements that are not occurring in the dataset ('virtual elements'), these are categories which are used to build the structure of a tree. The IDs of these virtual elements are UUIDs.
