1. An object that is immediately above another object in its group tree.
A group object is the parent to each of the objects that compose it. Every
object is the parent of its children.

particular value in a hierarchy. The parent value is the aggregated total
of the values of its children. The following example shows the dimension
value "France" as the parent of "Lyon" and "Paris"
