Ulrich Frank and Pierre Maier presented the multi-level-modeling tool XModelerML at this year’s German-speaking Fachtagung Modellierung 2026. Special emphasis has been put on the tool’s application for modeling education. For this purpose, additional learning materials have been design and published under https://www.wi-inf.uni-due.de/LE4MM/educational-material/. Summary of contribution (translated from German): “This paper presents XModelerML©, a language development, […]

Pierre Maier presents a paper on “Model Deepening with Large Language Models: Insights from Exploratory Studies with ChatGPT” at the 44th International Conference on Conceptual Modeling (ER 2025). The publication ic co-authored by Vicky Kadziolka. Although multi-level modeling has long been argued to showcase benefits in various application domains, its adoption is still hindered not […]

XModelerML version 3 has been released. With version 3, it is now possible to switch between two-level and multi-level modeling modes. Diagram types can be changed by right-clicking on a diagram in the Control Center and selecting “Make UML++/FMMLx Diagram.” The UML++ diagram editor now offers a new “UML Meta Mode.” In UML Meta Mode, […]

Together with Tony Clark from Aston University Ulrich Frank teaches a tutorial on “Multi-Level Modeling and Language Engineering Promoting Reuse, Integrity, and Flexibility of Languages, Models and Software Systems” at this year’s Entity Relationship Conference (ER 2025) in Poitiers, France. The tutorial offers an introduction to multi-level modeling and corresponding multi-level language architectures. They make […]

Ulrich Frank teaches a tutorial on “Simultaneous Development of Languages, Models, and Programs: Boosting the Power of Modeling” at this year’s Models Conference in Grand Rapid, MI (Homepage of Models 2025 Conference). Usually, the development of DSMLs is separated from the development of corresponding models, resulting in two different representations that are not integrated. Hence, […]

The 12th International Workshop on Multi-Level Modeling (MULTI 2025) has been accepted as part of this year’s ACM/IEEE International Conference on Model-Driven Engineering Languages and Systems (MoDELS 2025). The conference will take place at the University of Michigan in Ann Arbor, United States. The workshop is co-organized by our team member Pierre Maier. MULTI is the […]

Version 2.4 of XModelerML has been released on March 28, 2025 and is available for download from the LE4MM portal. The new version significantly expands the tool’s range of functions. XModelerML and UML-MX are now available under a common interface. Users can choose between UML++ and FMMLx at runtime. In addition, class hierarchies can now […]

Common (meta) modeling languages do not allow the definition of specific association types. This restriction is sometimes a serious disadvantage for the design of DSML Daniel Töpel presented the paper “Association Types: Motivation, Specification and Implementation with the XModelerML” at the MULTI workshop in Linz. It describes an extension of FMMLx, a multi-level language developed […]
