Astract: Conceptual modeling is widely adopted in industrial practices, e.g., process, software, and systems modeling. Providing adequate and usable modeling tools is essential for the efficient adoption of modeling. Metamodeling platforms provide a rich set of functionalities and maturely realize state-of-the-art modeling tools. However, despite their maturity and stability, most of these platforms only slowly - if at all - leverage the full extent of functionalities and the ease of exploitation and integration enabled by web technologies. With the Graphical Language Server Protocol (GLSP), it is now possible to realize much richer, advanced opportunities for visualizing and interacting with conceptual models. This paper presents a concept and a prototypical implementation of two advanced model visualization and interaction functionalities with the Eclipse GLSP platform: Semantic Zoom and Off-Screen Elements. We believe such advanced functionalities pave the way for a prosperous modeling future and spark innovation in modeling tool development.

Astract: Enterprise Architecture offers guidelines for the coherent, model-based design and management of enterprises. EA models provide a layered, integrated, and cohesive representation of the enterprise, enabling communication, analysis, and decision making. With the increasing size of EA models, automated analysis becomes essential. However, advanced model analysis is neither incorporated in current EA methods like ArchiMate nor supported by existing EA tools like Archi. Knowledge Graphs (KGs) can effectively organize and represent knowledge and enable reasoning to utilize this knowledge, e.g., for decision support. This paper introduces a model-based Enterprise Architecture Knowledge Graph (EAKG) construction method and shows how starting from ArchiMate models, an initially derived EAKG can be further enriched by EA-specific and graph characteristics-based knowledge. The introduced EAKG entails new representation and reasoning methods applicable to EA knowledge. As a proof of concept, we present the results of a first Design Science Research Cycle aiming to realize an Archi plugin for the EAKG that enables analysis of EA Smells within ArchiMate models.

Astract: This paper introduces the first major release of the bigER modeling tool. bigER offers various features for flexibly specifying and visualizing Entity Relationship (ER) data models. Within the Visual Studio (VS) Code IDE, the tool enables hybrid modeling through a textual editor and a graphical editor to display and modify the textual and graphical ER model, respectively. Both editors are realized with a custom language to specify ER elements and allow multi-notation support (currently Bachman, Chen, Crow’s Foot, Min-Max, and UML). The bigER modeling tool incorporates the Language Server Protocol and is based on web technologies, which makes the tool platform-independent and easily extensible. We present the newest extensions of bigER, i.e., multi-notation support and improved edge routing.

Keywords: Enterprise Architecture Management, Education, Survey
Astract: Enterprise architecture (EA), although matured in more than 30 years of ongoing research, receives more importance with the increasing dependency of business in IT and the growing complexity of IT systems. The integrated management of a companies’ goals, structures, and processes with respect to the business and IT elements, as well as the representation of impacts triggered by planned changes is educated in different ways at many universities all over the world. There are several techniques, methods, tools, and approaches to transfer the knowledge from the educators to the students, giving them the qualification to support their future employers in handling the EA challenges modern companies are facing. This work gives a detailed comparative analysis of more than twenty international educational offers regarding Enterprise Architecture Management, carves out the commonalities and finds two prototypical courses as a best-practice combining the strongest matches for Business Informatics and Computer Science studies alike.
