SIMMA is a Java framework for simulation of roboters and their behavior in an arbitrary environment. The simulator can be configured by Java property files to run various robotic experiments, which results in a quite large number of configuration files. Work in this project should be aimed at ``condensing'' all configuration information in a single XML file fully describing the desired simulator setup. Also, recently added evolution support in SIMMA should be integrated in the configuration file. The syntax should allow for future extensions of the framework. As a final proof of concept a migratory bird simulation should be implemented and run in the simulator based on the XML configuration.
