National Data Platform (NDP) addresses the challenge of data and computing resource integration facilitating the nation's capacity to pursue scalable AI-driven discovery and innovation by establishing a federated and interoperable ecosystem that connects distributed data repositories and computing facilities across the U.S. NDP will reduce barriers of entry for data-driven science and enable researchers, educators, and learners to accelerate their research and innovation objectives. It will expand access to advanced capabilities and unlock the nation's full research potential across regions, institutions, sectors, and disciplines. NDP will also enable hands-on experiential learning, curriculum development, data challenges, and workforce training aligned with national priorities in AI and data science. By federating existing public investments and engaging private resources into an accessible AI innovation ecosystem, NDP will strengthen U.S. competitiveness and expand both research participation and workforce engagement in an increasingly AI-driven world. NDP will integrate geographically distributed data, computing, and AI resources and services into a cohesive, federated framework that supports end-to-end, AI-enabled scientific workflows. This will be delivered through interoperable, production-grade services and middleware that streamline secure access, integration, composability, and use of data, models, and workflows across edge, cloud, and high-performance computing
