The U.S. National Science Foundation has announced the launch of the NSF Open Knowledge Network, a federated system that links 43 separate knowledge graphs. Developed through the Prototype Open Knowledge Network program and in collaboration with a broad coalition of federal partners, the network is now open for public use as of September 28, 2026.
By connecting these knowledge graphs, the network is intended to support cross-domain queries and analysis that would be difficult or impossible within isolated datasets. The NSF frames the effort as a step toward a more integrated research infrastructure, though the announcement does not specify which graphs are included or what technical interfaces are provided.
Because this is a single source, there are no independent accounts to compare against. The details provided are limited to the program's origin, the partnership structure, the number of graphs, and the public availability date.
