By 2030, Metaverse operations will be commonplace at leading airports where they will play a vital role in optimizing processes and resources, avoiding disruption and facilitating immersive, contextual, and intelligent control – to meet increasing demand. This multi-consortium Catalyst will address the challenges faced by businesses wanting to create and capture value in the Metaverse, including interoperability, sustainability, scalability and real-time, trusted data sharing. The Catalyst will refine a reference architecture and implementation for an event-driven system of systems delivered through a federated services marketplace based on the DBM initiative and TM Forum Open APIs. These services will incorporate Industry 4.0 and Metaverse technologies including 5G, MEC, extended reality, artificial intelligence, IoT, digital twins, event-driven architecture, and robotics to improve passenger experiences and decision-making. The zero-touch reference implementation will model and demonstrate: * 50% reduction in passenger queues and wait times via modeling and simulation. * 20% increase in passenger services revenue via a mobile app and recommendation engine. * 50% reduction in Industry 4.0 implementation costs and time-to-value via marketplace governance.
