+      <overview
+          summary="The VIATRA framework supports the development of model transformations with specific focus on event-driven, reactive transformations. Building upon the incremental query support using the Rete algorithm, VIATRA offers a language to define transformations and a reactive transformation engine to execute certain transformations upon changes in the underlying model."
