Abstract: Collaborative development, incremental design and
revision management require the ability to compare different
versions of software artifacts. There are well-established
approaches for comparing textual artifacts such as program files.
However, the situation is different in graphical modeling. So far
there exists little support to compare models visually-graphically
in the model diagram itself. This paper presents several possible
approaches and explores one of these in further detail.We apply
paradigms of visualizing text files side-by-side to graphical
diagrams and enhance the views by additional features such as
automatic layout, navigation and folding. These means allow to
compare even complex models without missing differences or getting
lost in text based structure compares.As a proof of concept, the
proposal is implemented in KIELER, a prototypical modeling
environment based on Eclipse.
