The Department of Defense (DoD) is seeking proposals for the Chief Digital and Artificial Intelligence Office (CDAO) Data Mesh Reference Design (REFDES) under the Small Business Innovation Research (SBIR) program. The objective is to develop a set of software services that enable data users across the DoD to discover, understand, access, and consume data products in a zero-trust environment, moving away from traditional data sharing models to a more modular "Data Mesh" approach. This initiative is crucial for enhancing data interoperability and operational efficiency within the DoD, supporting applications in both military and administrative contexts. Interested parties should note that the solicitation is currently closed, with the application due date having been May 15, 2024, and further details can be found at the DoD SBIR website.
