An M3-neutral infrastructure for bridging model engineering and ontology engineering

In this paper we report on some research activities in the ATLAS team in Nantes and the GOOD OLD AI research group in Belgrade in the domain of model-based engineering. We start from the idea that a convenient organization of various technical spaces in three "metamodeling" layers offers a convenient working environment. The main message of this paper is that it is possible to consider software engineering and ontology engineering as two similarly organized areas, based on different metametamodels (M3level). Consequently, building bridges between these spaces at the M3-level seems to offer some significant advantages that will be discussed in the paper.
