The goal of this phase of the Cyber-Physical Systems Virtual Organization (VO) is to sustain and enhance the web-based platform of the research communities of Cyber-Physical Systems and Smart & Connected Communities. The approach is to enable collaboration among PIs, disseminate project results of Principal Investigators (PIs) and their teams, and amplify research outcomes tied to those projects. The project will build on previous efforts to maintain the sites and ensure platform stability. The site will preserve archival access to past and current resources and continue to provide services to the communities. These services include sharing data, tools, publications, educational materials, and events. This phase will strengthen the VO’s ability to help researchers find, understand, and reuse community outputs. The approaches include improved search and data organization. Outreach and engagement activities will continue to gather and highlight new research results. This coordination will foster interdisciplinary participation, and enable new collaborations among academia, industry, and government stakeholders. Through these approaches, the VO will continue to be a stable, trusted hub that responds to sponsor priorities and community needs. Intellectual Challenges addressed by this new phase of the VO include the following. (1) Maintain a resilient, secure, and scalable cyberinfrastructure. This will support long-term community access, while adapting to evolving requirements
