the uml2 standards aren't really ready for prime time just yet. i'd hold off 
for about a year before getting seriously involved with them. they're still 
working out some issues and they haven't published the xmi specifications of 
the various components yet - i hope they do soon.

there should be a number of components to any tool that implements these 
standards. my thesis project revolves around a complete implementation of the 
data models for the uml 1.x family of standards (including mof and xmi) - no 
ui stuff at all. it's called the open modeling framework (OMF) and the 
"pre-pre-pre alpha" can be found at http://www.cs.kent.edu/~asutton. its my 
hope that umbrello adopts the omf as the underlying object models for some 
future release.

i haven't decided whether or not i'm going to extend my work to cover the uml2 
family of standards. i think there are enough differences between 1.x and 2.0 
that it would require a complete rewrite. I know the internal structure of 
the object models has changed significantly.

no docs just yet. i've been waiting til i get to a stable release before i 
start working on the programmer's manual for my stuff. certainly no docs for 

i will say this... the uml standards favor languages like java and c# for 
implementation. coding these object models in c++ poses some significant
