This is not already used from David's (and his HotWax Media partners) recent great gift :
http://docs.ofbiz.org/display/OFBTECH/Advanced+Framework+Transcription+Work+PlanOkay dependent-on. This is not used right now, but it is
part of kind of a theory of a data model, where you can
specify that this entity is dependent on some sort of a
primary entity. And the intent was to use this for things
like data exporting or other such things, to automatically
follow a tree of entities and do something with them as
a group. But nothing is really implemented based on
this right now.
Okay and the same, you'll note that the view entity also
as a dependent-on field. Same situation there; nothing
is really using it. But it was part of the initial design, as
part of the theory on how a data model can fit together.
