Abstract
Today's software development and maintenance is time consuming,
cost-intensive and particularly an iterative process.
Since models and diagrams are the main artifact in the development
process of numerous research institutes and software
companies, it is necessary to show and merge differences as
the model evolves. While there are plenty of difference tools
available for textual artifacts (like source code) this does not
hold for diagrams.
This paper presents an approach to show and merge deltas
of different model versions directly within the corresponding
diagram editor. This is done by integrating the Difference
Visualization for Models (DVM) framework into existing editors
with as little effort as possible.
