My Test Assembly” is the parent of owned
component “My Test Component 1 IH” and
published component “Owner Status Test”.
“My Test Component 1 IH” and “Owner
Status Test” are therefore child nodes of “My
Test Assembly”.
Continuing, “My Test Component 1 IH” is
the parent node of published material
“+ZA130 (hot-dip zinc-aluminium coated)”
and published material “St 37-2 G”.
Note that each “layer” consists of all the
same “type”, with layer one and two
components, layer three materials, and layer
four (the bottom layer) basic substances.
Basic substances cannot ever have children,
even other basic substances.
