Dear Heiko,

yes, it would be great to offer some kind of a big picture to ease people
understanding how the models fit together. I think this should be part of
the introduction document.

The idea of my submission [1] was indeed to depict the relations between
the models. Even if all models can be seen independently (GR1:Completeness)
in practice it would be hard to design an AUI without even thinking
about the
actual domain (model).

I absolutely agree with Jean, that the domain model is separate and
independent - often it already exists (at least partially) even before an
interface is designed. Thus, my proposal was to factor out of  the "id"
attribute of the
AUI model to an "entity" that every other model element from every model
is related to
(e.g. by inheritance or association)  and that is used to define mappings
(and/or transformations) between elements of models.

In my opinion, documentation, the domain model, the localization, and even
the behaviour are not part of the AUI model (because these concepts are
relevant for
other models as well) but could be connected in an elegant way by using

Pls. note that [1] was a submission of my personal understanding of the
AUI to illustrate my idea
and is neither complete nor a shared view between the group participants.
