Abstract
Abstract. Model-Driven Engineering (MDE) introduced the notion of metamodeling as the main means for defining modeling languages. As a well organized engineering discipline, MDE should also have its theory clearly defined in terms of the relationships between key MDE concepts. Following the spirit of MDE, where models are first class citizens, even the MDE theory can be defined by models, or so called megamodels. In this paper, we use Favre’s megamodel that was already used for defining linguistic metamodeling. Starting from the premise that this megamodel can also be used for defining other MDE concepts, we use it to specify the notion of ontological metamodeling. Here, we show that in order for this megamodel to be able to fully capture all the concepts of ontological metamodeling, some refinements should be applied to its definition. We also show how these new changes are in the same direction with the work of Kühne in defining linguistic and ontological metamodels.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
