The Task Area Community Interaction (TA-CI) is the central hub for engaging the interdisciplinary MSE community. Its goal is to build broad acceptance of NFDI-MatWerk and involve researchers across all career stages and domains. TA-CI emphasizes that NFDI-MatWerk is not just data collection but a framework for knowledge creation through FAIR, high-quality data practices. It supports stakeholders with onboarding, identifies needs, connects them to infrastructure use cases, fosters dialogue on new developments, and promotes integration into the wider NFDI and oneNFDI ecosystem.
