Although traceability is often a suggested requirement for general software development, there are areas such as airborne systems, where traceability is a compulsory part of the development process. This paper describes a tool chain that is able to generate and to follow traceability links across model-to-model and model-to-code transformations, and capable of providing navigability support along these traceability links. We elaborate on the conceptual design of our tool chain and provide details on its realization in a DSML environment underpinned by graph rewriting-based model transformation.
