  abstract  = {Design models must abide by constraints that can come from diverse
	sources, like metamodels, requirements, or the problem domain. Modelers
	intent to live by these constraints and thus desire automated mechanism
	that provide instant feedback on constraint violations. However,
	typical approaches assume that constraints do not evolve over time,
	which, unfortunately, is becoming increasingly unrealistic. For example,
	the co-evolution of metamodels and models requires corresponding
	constraints to be co-evolved continuously. This demands effcient
	constraint adaptation mechanisms to ensure that validated constraints
	are up-todate. This paper presents an approach based on constraint
	templates that tackles this evolution scenario by automatically updating
	constraints.We developed the Cross-layer Modeler (XLM) approach which
	relies on incremental consistency-checking. As a case study, we performed
	evolutions of the UML-metamodel and 21 design models. Our approach
	is sound and the empirical evaluation shows that it is near instant
	and scales with increasing model sizes.},
