Abstract : Building a UML profile is tedious and error-prone. There is no precise methodology to guide the process. Best practices recommend gathering concepts in a technology-independent domain view before implementation. Still, the adequacy of the implementation should be veriﬁed. This paper proposes to transform automatically a domain model into a profile-based implementation. To reduce accidental complexity in the domain model and fully beneﬁt from advanced profiling features in the generated profile, our process relies on the multilevel paradigm. The value of this paradigm for the definition of UML proﬁles is assessed and applied to a subset of the Marte time model.
