[FLOW3-general] Building Trees with flow/doctrine

[Aike Terjung]

Hello,

i'm new to typo3 flow and i am trying to implement a new application at 
the moment, wich should base on an object tree. From my OO knowlege i am 
used to build such trees with nested objects. In the flow universe, im 
not shure how to do this.

Lets say i would build the tree like this:

Root
  -Node
  -Node
    -Node
    -Node
      -Node
      -Node
  -Node

nothing special i think. But - how to implement? I would like to start 
with a abstract basemodel like "treenode" and extend the different types 
of Nodes, "dokument" - the root, and "fragment" - the nodes. Is this the 
right way to do it with flow?

And will it be bersisted as it should?

thanks in advance

Aike
