first of all - sorry for the big delay in responding to the last post of
Nicolas. Thank you Nicolas for giving interesting insights into the past and
into the current state of your project.
I'll try revive the discussion buy just commenting some of Nicolas'
Since we have very common goals and we mostly agree in all points, I'll only
comment on those parts of the post, that should/can be clarified.

Yes, I also meant all the objects in the "worksheet" - plots, curves etc.

By model/view I meant the following design pattern:

I think, the merge of both projects is not an option, since nobody of us
will be ready to completely give up the own project. Since there was no
response from kst's developers I conclude that there is no real interest in
our code. The possible collaboration can consist of sharing of ideas or just
of looking into the foreign code to get some ideas, inspirations or solutions
of own problems. The sharing of the code is more problematic, since the code
basis in the backends is quite different.
You mentioned the kipi-plugins and the idea of having some common frameworks
that can be used in plotting programs. There is already something that can
probably be used in projects we're working on:
I didn't manage to find the time to understand this framework in all the
details. But I've got a sketchy overview of it and I think, that it'll be
possible to combine the current labplot code with the flake interface. The
painting is impelemented as in the current code and in addition the flake
interface is put onto it and supported throughout the software. Having this,
it should be possible to import flakes from other programms.
For example, I would very appreciate the possibility of having a set of
Feynman diagrams in some of koffice-programms (this would make programms like
JaxoDraw obsolete for KDE-users) or some other vector objects und to
import/use them in labplot.
I stopped working on the plotting stuff until I find more time to look at
Also, it was planned to provide in labplot a high degree of interactivity like
in other vector graphic programms (e.g. like in karbon). This part turned to
be more complicated as I thought before and I postponed this job. A brief look
into the karbon's code was not very enlightening (say, I was not able to
understand everything within 20 minutes).
What are the plans for kst? Will such a degree of interactivity be implemented
at some point?
The idea of having common frameworks for plugins, scripting stuff etc. would
require a big amount of discussions and adjustments in the backends...
