Parents - children
Fieldsparents
and children
permit to manage subgroups.
The relation
child --> parent
is implemented with a direct acyclic graph (DAG), vendor/tiglib/dag.
The edges of this graph are "is child of" relations.
This permits to have several children and several parents.
Parent - child relations are used to classify occupations.
