less code is always better code :) which doesn't bode well for the omf which 
is currently topping the charts around 135 kloc ;)

here's my bibliography as of this morning when i started compiling it. i 
haven't mined out the references yet, so i'm sure there's tons of stuff i'm 


oddly, some of the definitions are starting to fit with some of the ideas in 
MDA - at least if you start substituting the word "domain" for the word 
"model". so any papers on MDA would also be a good starting point. it'll 
probably be nice to lookup stuff on reverse engineering with UML too since 
reverse engineering is one of the model transformation functions (source to 

right now, i'm just compiling some notes on how to build a rountrip 
implementation for kdevelop using the omf. naturally, the success of this 
project is going to depend heavily on the umbrello developers voting for (and 
actually starting on) a complete rewrite for the next major version of 
umbrello in the next month or two - and of course we'd have to use the omf as 
the underlying object model :)

actually, if you're interested in just working on roundtripping without the 
overhead of umbrello, the omf is in a pretty good state to do so. granted, 
there's no ui, but some of the original ideas can be built as command line 
tools - specifically for some of the initial work on reverse engineering. 
besides, i need a user other than myself :)

if you do decide that's something you'd be interested, we should probably talk 
about the overall design of a roundtrip component, what transformations are 
required, what parameters might be needed, etc, etc.
