    A Deep Perspective on the ArchiMate Modeling Language and Standard
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 2, 2020) Atkinson, Colin; Kühne, Thomas
    Given the scale, complexity and variety of enterprise architectures, approaches for modeling them need to be as simple and flexible as possible in order to minimize the accidental complexity within enterprise architecture models. Multi-level modeling techniques offer an effective way of achieving this but to date there has been little research into how they could contribute to enterprise architecture modeling. In this article we therefore explore how the former could be best leveraged within the latter by considering the modeling goals, architecture and principles of one of the most concrete and widely used enterprise architecture modeling standards: ArchiMate. More specifically, we discuss how the conceptual integrity of the ArchiMate standard and modeling experience could be enhanced using multi-level modeling principles. In our discussions, we focus on a specific variant of multi-level modeling, called deep modeling, which is based on the notions of orthogonal classification and deep instantiation.

    Multi-Level Modeling with Openflexo/FML
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 9, 2022) Sylvain Guérin, Joel Champeau
    Model federation is a multi-model management approach based on the use of virtual models and loosely coupled links. The models in a federation remain autonomous and represented in their original technological spaces whereas virtual models and links (which are not level bounded) serve as control components used to present different views to the users and maintain synchronization. In this paper we tackle the EMISAJ multi-level process modeling challenge, which consists in providing a solution to the problem of specifying and enacting processes. Solutions must fulfill a number of requirements for a process representation defined at an abstract process-definition level and at various more concrete domain-specific levels, resulting in a multi-level hierarchy of related models. We present a solution based on model federation and discuss the advantages and limitations of using this approach for multi-level modeling. Concretely, we use virtual models and more precisely the Federation Modeling Language (FML) that serves to describe them as the main building block in order to solve the process modeling challenge whereas the federation feature is used as a means to provide editing tools for the resulting process language. Our solution fulfills all the challenge requirements and is fully implemented with the Openflexo framework.

    Special Issue on Multi-Level Modeling Process Challenge
    (Enterprise Modelling and Information Systems Architectures (EMISAJ) – International Journal of Conceptual Modeling: Vol. 15, Nr. 4, 2022) João Paulo A. Almeida, Thomas Kühne
    Multi-level modeling is an extension of traditional two-level object-oriented modeling which over the years has spawned several related solution technologies. These technologies embody a variety of multi-level modeling approaches, with differences spanning the range between superficial detail to fundamental divergence. Understanding those differences, as well as the respective trade-offs of different technologies can be difficult when looking at each technology in isolation and/or when technology demonstration application scenarios are not standardized. This EMISAJ special issue invited solutions to a multi-level modeling process challenge (Almeida et al. 2021), in order to allow contributors to showcase advantages and discuss shortcomings of their technologies. The contributions featured in this special issue therefore do not only support a deeper understanding of each technology respectively, but in combination also support comparisons among technologies.
