ER 2026 (International Conference on Conceptual Modeling) is a CCF C / CORE A / QUALIS A2 conference held in St. John's, Canada on 2026-10-05. The paper submission deadline is 2026-05-05. Acceptance notifications are sent on 2026-07-14.
We welcome submissions of original research on a variety of topics on conceptual modeling. These include well-established areas of research and practice, such as modeling languages and techniques, model theories, methods and tools for developing, transforming, implementing and communicating conceptual models. Submissions that lead to new foundations, links, applications, or enlarge current boundaries of conceptual modeling are especially welcome.
In celebrating the conference’s 45th anniversary this year, we especially invite contributions on the theme of CONCEPTUAL MODELING AND SUSTAINABILITY . Conceptual modeling plays a critical role in sustainability by offering structured ways to represent and connect complex environmental, social, and economic systems. In a year marked by accelerating climate impacts, policy transitions, and technological change, models help researchers and practitioners align assumptions, compare scenarios, and translate knowledge across disciplines. Continuing a long tradition, ER 2026 will host workshops to be held in conjunction with the main conference. These workshops serve as an intensive collaborative forum for exchanging innovative ideas about conceptual modeling, and for discovering new frontiers for its use. We specifically invite proposals for interactive workshops on new, emerging, or established topics in conceptual modeling, or its application in specific domains. We encourage workshop organizers to include activities that provide their participants with a true workshop experience. Topics of interest include foundations of conceptual models, theories of concepts, ontology-driven conceptual modeling and analysis, methods and tools for developing, communicating, consolidating, and evolving conceptual models, and techniques for transforming conceptual models into effective implementations.
