Traceability as Input for Model Transformations

Some model transformations require more information than can be derived from its source model(s) in order to generate a meaningful target model. For example, a transformation with two source models needs to know how their respective model elements relate; these relations often only exist implicitly as part of the transformations developer’s knowledge. In this paper we show that traceability models, who can be automatically generated as part of any model transformation, contain explicit interand intra-model relations that are valuable to subsequent transformations. We explain how to extract this information and propose a number of additions to current transformation techniques that are needed to completely open up traceability information to transformation developers.
