Exemplary projects addressing these topics are the KIELER Structure-based Editing (KSbasE) and the KIELER Lightweight Diagrams (KLighD). The first one aims at providing operations for changing models based on its abstract syntax (introduce new elements, modify them in some way, connect them, or delete them). The second one targets the synthesis of graphical representations of models or model excerpts in a lightweight and transient way. This means, representation representations are synthesized on modelers the modeler's demand and dismissed later on without saving them on the discdisk, unless the modeler wants to do that. Both techniques are enabled by the ability of automatically arranging diagram elements as provided by our layout corner.

KAOM, the Kieler Actor-Oriented Modeling component, provides a viewer for data flow diagrams. Its primary use is to provide a realistic application for our layer-based layout algorithm. Through KARMA, the Kieler Advanced Rendering of Model Appearance component, we can make sure the data flow diagrams look very similar to what they look like in other tools. We primarily support the import and displayal display of Ptolemy models.

Finally, the Graphs provides a simple editor for diagrams. It is used during the development of layout algorithms.
