When executed on a model, a particular model operation rarely touches all elements contained in its input models. The set of elements touched during its execution forms its footprint. In [1], we motivate the use of footprints in modeling activities to detect problems with a model's scope or level of detail or the presence of fault in an operation.
We presented two approaches for footprinting operations: dynamic footprinting reveals the actual footprint of a model operation after its execution, while static footprinting estimates the footprint of an operation before its execution. To investigate the footprints of real-world models and evaluate the precision and efficiency of static footprinting, we conducted a case study and some experiments involving 75 Ecore models and 5 operations written in Kermeta:
This website provides access to the materials presented in [2] (implementation of algorithms, models and model operations) necessary to replicate the results presented in [1]. It does not contain a comprehensive introduction to footprints, neither a detailed presentation of algorithms involved in footprinting.
