Abstract
Extension is a common term used in model-driven engineering. However, it is expressed in different ways by different modeling languages. A class diagram modeler uses extension to mean inheriting from a class. An aspect modeler extends a base with an aspect. Despite the different ways the term is being expressed, it generally refers to adding/changing structure/behaviour of a model in some way. We observe that model extensions vary in several ways. For example, in some cases, such as in use case diagram extensions, the extended model (base model) is information complete, meaning that it requires no further information in order for it to be useful. In other languages, the base model is not useful on its own and must be completed with an extension. Extensions also vary in terms of granularity, e.g., inheritance between two classes is an extension at a low level of granularity (between two elements, i.e., classes, of the same class diagram) compared to extension between two models. This paper presents a feature model for extensions in modeling languages. We discuss how extensions vary in terms of granularity, the completeness of the base model, whether or not the extension model requires to specify matching information, and the changes the composed model does to the base. Using this feature model, we explore extensions in several popular modeling languages and report our findings.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
