Data Structure Documentation?

Hello!

In templates and reporting pages I see a lot of object bits like
$Ticket->OwnerObj->NickName; I’ve gleaned a few from reading code and
templates, but I’ve never tripped over documentation of the structures.
perldoc’g the modules seems to get me the function members only.

Is there any such documentation? If not, I’ll try to pull some together if I
can figure out how to deduce it completely and accurately.

Thanks!
