Abstract

The purpose of this paper is threefold: (1) to show a methodology for introducing formality step-by-step, starting from a "light-weight'' ontology, (2) to apply it to the generic Route Graph model, instantiated here to Tramway Networks, and (3) to demonstrate that separation of concerns into layers of abstraction and application of generic formal notions such as graph abstraction lead to a useful decomposition of safety properties.
