First, this is a nifty idea. Objectifying this is long overdue. But I was
struck wondering, is this trying to objectify the current dat format as it
is, or an ideal one as we would like to see it be...
Also, are you a fan of the MVC paradigm/pattern? (I am... MVC = Model View
Controller)
If you are, are all these classes supposed to be part of Model? Stuff like
the renderer class seems more part of View, either you may have some
muddiness, or I may not be seeing intent clearly.
If you're not, let's talk further... LDraw seems a natural application of
the MVC pattern.
Also, do you have an object diagram whipped up that you can share? I find
when I'm modeling it's often better to start from an object diagram and let
inheritance take care of itself. Relations among objects are often the most
important things about them.
