Building on fundamental innovations in the study of the intersection of chemistry and data science, the Community Resource for Innovation in Polymer Technology (CRIPT) project built a stable and scalable data ecosystem that makes polymer data widely available to and usable by a broad community. The current project, the Community Resource for Innovation in Materials and Chemistry (CRIMaC), substantially enhances CRIPT to grow beyond the community of 160,000 polymer researchers into a tool that potentially enables millions of innovators in chemistry and materials research to find data faster, collaborate more easily, and to use trustworthy data to drive innovations in artificial intelligence, machine learning, and automation. CRIMaC includes innovations to address user needs for visualization and data reliability, and its functional scope is broadened through extensions of innovations in data science originally developed for polymers to be relevant to chemical and materials science data more broadly. The technical innovations and cyberinfrastructure operations are coupled with educational and outreach efforts to grow the CRIMaC user community, including curricula material for undergraduates, online tutorials for self-learning, and train-the-trainer opportunities for advanced users and instructors. CRIPT is a stable, scalable, and robust platform for polymer data based upon key innovations in data structures, molecular representations, search technologies, and similarity rank
