As software becomes increasingly complex, automatic documentation of the development is becoming ever more important. In this paper, we present a novel, general strategy to build a revision control system for the development of numerical models for scientific applications. We set up a formal methodology of the strategy and show the consistency, correctness, and usefulness of the presented strategy to automatically generate a documentation for the evolution of the model. As a use case, the proposed system is employed for managing the development of hydrogeological models for simulating environmental phenomena
within a research environment.
