(FC-Devel) Core features...

["Dr. Thomas Fricke" <Thomas.Fricke@oen.siemens.de>]

Hello all,

in my opinion Chen Ofek and me are very close together, 
even if we seem to have different names for the same thing.
So I cited Chen Ofek's opinion with some of my additional 
questions.

Is this the place where the UML (or pattern parts) are living?

... and finally, is this the code generating and reengineering
domain? I am not sure, if this translations are the intended 
meaning.

I have vague ideas about this part...

This would be really exciting.

I agree, that they are not so important for the 0.99 versions. I think,
these problems could be solved later without changing the whole model.
For some of the problems I really have seen some solutions working.
The main ideas can be collected and be brought together.

This could be the point, were we really can start working together. I do
not
even need the graphic stuff at the beginning and would even be happy
with some text descriptions. We can start designing the viewing layer to
see
the diagrams as pictures with the tool inside.

I think, this will speed up the development dramatically. So, we should 
start the first diagrams to design the first common patterns. I do not
know
if we should start immediately. However, there has been a discussion
some
days ago. What do you think about the inheritance modeled by Chen?

I have proposed an inheritance pattern, which have not looked general
enough.
However, trying to read the answer in details, I see, that I have not
understood
the answer... Hmmm, anyone can help me? 

I think, we should start with an example (why not inheritance?) to see
the concept at
work...

Bye everybody
