Child properties form the composition tree. All objects need to be a child of another object. Objects can only be a child of one object.

There is no way for a child to determine what its parent is. It is not a bidirectional relationship. This is by design.

The value of a child property as a C string will be the child object’s canonical path. It can be retrieved using object_property_get_str(). The child object itself can be retrieved using object_property_get_link().
