It's derived from Abstract Oriented Design. I published a paper on such 
to USENET in the '90s, so this isn't anything new to me. The paper 
merely pinpointed the need for real object oriented design to be active 
before abstract oriented design can be achieved. That's said passive 
because the main point is the flat model most people think is object 
oriented design is not sufficient for true OOP.

AOD is something even JavaVM couldn't achieve while limited to its flat 
text orientation model for program design. JVM added some hooks into the 
language to simulate such, yet even that attempt proved JavaVM wasn't so 
original and based upon many ideas they never credited nor implemented 
first (which finally forced Sun to open source).
