    Collaborative Modeling Enabled By Version Control
    (Modellierung 2018, 2018) Kuryazov, Dilshodbek; Winter, Andreas; Reussner, Ralf
    Model-Driven Software Development is a key field in software development activities which is well-suited to design and develop large-scale software systems. Developing and maintaining large-scale model-driven software systems entail a need for collaborative modeling by a large number of software designers and developers. As long as software models are constantly changed during development and maintenance, collaborative modeling requires frequently sharing of model changes between collaborators. Thereby, a solid change representation support for model changes plays an essential role for collaborative modeling systems. This paper focuses on the problem of model change representation for collaborative modeling. It introduces a meta-model generic, operation-based and textual difference language to represent model changes in collaborative modeling. This paper also demonstrates a collaborative modeling application Kotelett.

    Collaborative Software Modeling in Virtual Reality
    (Software Engineering 2022, 2022) Yigitbas, Enes; Gorissen, Simon; Weidmann, Nils; Engels, Gregor
    This work has been published as a full paper at the MODELS'21 conference. Through collaborative modeling, end-users and experts can create a shared understanding of a system representation. While the Unified Modeling Language (UML) is one of the major conceptual modeling languages in object-oriented software engineering, more and more concerns arise from the modeling quality of UML and its tool-support. Among them, the limitation of the two-dimensional presentation of its notations and lack of natural collaborative modeling tools are reported to be significant. In this paper, we explore the potential of using Virtual Reality (VR) technology for collaborative UML software design by comparing it with classical collaborative software design using conventional devices (Desktop PC / Laptop). For this purpose, we have developed a VR modeling environment that offers a natural collaborative modeling experience for UML Class Diagrams. Based on a user study with 24 participants, we have compared collaborative VR modeling with conventional modeling with regard to efficiency, effectiveness, and user satisfaction. Results show that the use of VR has some disadvantages concerning efficiency and effectiveness, but the user’s fun, the feeling of being in the same room with a remote collaborator, and the naturalness of collaboration were increased.
