Subject: Re: [dsdp-mtj-dev] MTJ Model
The description of generating the model code is in CVS at dev.eclipse.org /cvsroot/dsdp/org.eclipse.mtj/mtj-home/docs/MTJ_model_codegen.ppt
It is a decent start to get you generating the model, although a few of the steps are missing or in the wrong order.
The architecture documents that you should be looking at for more basic understanding are in the same directory, You will need to check the datestamps from CVS to determine which one is the last, but look at the MTJ Release 1 Architecture* documents for an intro, or the presentations we have one the eclipse/MTJ website that we gave at EclipseCon.

Arto,
Can you please point us at the explanation you gave before (mentioned by
Kevin)? Maybe we can read up on this before the meeting.
During the meeting - It would be good if you could get us all on the
same page. I agree we should take a few minutes to address this central
component of MTJ.
Is there any presentations you have which you can send out before the
meeting?
Please assume that most of us are not familiar with the details of EMF.
Thanks!
