Cross-Model Traceability for Coupled Transformation of Software and Performance Models
Bibliographic record
Abstract
In Model Driven Engineering, the relationship between a source and target model can be maintained, when the source model undergoes changes, by a coupled transformation, whereby changes applied to the source model are incrementally propagated to the target model. Cross-model traceability links are key to applying the correct changes to the target model. The coupled transformation considered in this paper propagates changes to a Layered Queueing Network (LQN) performance model (originally derived from a UML design model of a SOA system) as an effect of applying design patterns to the SOA model. A special problem arises because of differences in the level of abstraction between UML and LQN (i.e. a performance model element may represent a set of many design model elements). This paper bridges the abstraction gap between models by proposing traceability links that use new collection types (not defined in the source metamodel) to represent complex source model elements, which are then mapped to simple target model elements.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
