X.500 hierarchy

Does someone have a cookbook for representing this kind of hierarchy with a list? Hierararchy is defined by parent rowID in the child row. If possible, the structure depth shouldn’t be limited. Of course, this should be applied online (i.e. in app itself, not by offline copying into spreadsheet)!

You might want to approach this with a child column and a parent column.
