Dear Rich,
Thanks a much for your quick reply.
Actually I have looked at those items already. It is not the architecture
that confuses me (edges, nodes, etc). It is the meaning of the attributes
that are in those classes (for example how bendpoints are used, the
coordinates system, etc).
For example in our diagram we have connections that have 4 attached labels
(similar to an association/roles labels). In the old format, each label
was positioned using an integer that represented the distance between the
center of the label and a certain point on the connection. I would like to
understand -let's say the maths- of the notation model, so that a
conversion algorithm could be developed.
I hope I can find some kind of doc regarding this. Otherwise the only
solution that remains is reverse engineering of the code that does the
drawing on the screen (to be honest I am not very thrilled by this
perspective :) ).
I understand that the notation model was contributed by IBM originally,
and I think that they must have had some written specs for it (like the
Diagram Interchange format by the OMG).
Any leads?
Thank you.
Best regards,
Cristian.

Well, it's not based on the DI spec, and I've never seen such documentation
for the notation model. And if you've seen the doc I suggested, I'm
assuming you've read up on the use of HiMetric units as well. Unless
someone from the runtime team can dig something up, I guess it's time to
look into the code ;)
