Now-a-days, model-based implementation approaches are widely used. Many of these approaches allow specifying several models, each emphasizing one specific aspect of the system. To keep an overview on complex E-Commerce collaborations several models are used to describe them. When models overlap in describing collaboration, the overlapping information should not contradict. Models are of different nature and maintained by different people. Therefore, keeping model-overlap contradiction-free is challenging. In this paper, the authors propose a novel approach for maintaining models representing E-Commerce collaboration. Applying this approach supports avoiding contradictions in models during evolution of E-Commerce collaborations.
