Class diagram of the core of the data model

The image shows the core classes of the data model and how they are related. The methods of each class were left out for clarity.

Javadoc API

The automatically generated, always up-to-date Javadocs give a well-known view on the classes. The implementation of the model can be found in the package de.sonivis.tool.core.datamodel.
