First, forgive the question ... I'm slowly learning how to build a module up from scratch for a project I'm working on ... picked up the "Pro Drupal 7 Development" book to give me a quasi-basis, but am still very raw ...

The module I'm building will need to create three node types, Node3 chilld to Node2 child to Node1 ...

All I'm asking for here is pointers to how I would setup my module.install file to setup the inheritence as part of the install ... I didn't see anything in the README file that was 'low level', it was all stuff to do *through* the interface ...

Thx ...
