Triskell hence contributed to the software engineering community's effort to propose new ways of composing software from modeling elements, including for cross cutting concerns, that would unify the composition ideas behind Model Driven Engineering, Aspect Oriented Modeling, Software Product Lines etc  . Several research prototypes (http://www.kermeta.org/kompose/,http://www.kermeta.org/mdk/ModMap/) have been built to provide new composition operators. In the Mickael Clavreul PhD  , we define a framework to unify and classify existing model composition operator and ease the definition of new model composition operators. Theoretical basis to such a framework have been recently based on category theory in  .
