This $300,000 Project Grant from the National Science Foundation's Technology, Innovation, and Partnerships program (CFDA 47.084) will fund the establishment of an open-source ecosystem for the Interdisciplinary Networked Community Resilience Modeling Environment (IN-CORE) model. IN-CORE is an open-source modeling environment that can comprehensively model a community's physical, social, and economic systems and their complex interdependencies. This Phase I award will support initial focus group meetings and governance planning to launch the IN-CORE open-source ecosystem through August 2023. Key activities include validating metrics for success, engaging stakeholders, and partnering with a consultant to identify appropriate organizational and governance structures to scale the ecosystem. $30,000 of the funding was also allocated as a sub-award to the University of Illinois to support Dr. Jong Lee's leadership of the project in developing the open-source ecosystem plan and coordinating the founding committee. The open-source ecosystem is intended to accelerate adoption of community resilience modeling and enable new research through collaborative contributions and data sharing.
