Research

Jjodel is a research project developed at the SWEN group, Università degli Studi dell'Aquila. It investigates how to reduce accidental complexity in model-driven engineering tools through a reflective, cloud-native, and collaborative approach. Jjodel is part of EU-funded research and has been published in peer-reviewed venues including Software and Systems Modeling (SoSyM).

Projects

AIM-PRO

AI Literacy for Multidisciplinary Professional Readiness and Outreach

• Funded by the European Union (EACEA), Grant Agreement 101245864
• Duration: 36 months
• Coordinator: Università degli Studi dell'Aquila
• Partners: 15 organizations across 10 European countries

AIM-PRO develops educational frameworks integrating AI literacy with Model-Driven Engineering. Jjodel serves as a core learning tool in the project, enabling students and educators to work with metamodeling directly in the browser without installation barriers.
