“…A considerable number of publications demonstrated clear advantages of applying multi-level modeling to particular use cases, e.g., [18,27,31,32,44,60,65,67,90,98,100], and supported Atkinson's and Kühne's claim that "there is a strong demand for some kind of technology supporting ontological multi-level modeling" [9, p. 357]. However, while various approaches to multi-level modeling are available, it seems still to be the case what the authors stated 12 years ago: "[…] the software modeling community has not taken advantage of them yet" [9, p. 357].…”
