Making Open Research Work

CHORUS brings together funders, societies, publishers, institutions, and the public from across the open research ecosystem to share knowledge, develop solutions, advance innovation, and support collective efforts.


  • Provide trusted information about the outputs of funded research
  • Help funders, institutions, publishers, and the public see, find, and understand the status of the outputs of funded research
  • Identify research outputs that are easily and permanently discoverable and accessible by anyone in the world
  • Minimize compliance burdens for researchers, institutions, funders, and publishers
  • Deliver optimized search and dashboard services for monitoring and compliance


CHORUS collects information about published articles and data, and provides visualization tools that help users understand these outputs related to funded research.

CHORUS uses open technologies to optimize content discovery, long-term accessibility, funder identification, compliance monitoring, and dashboard reporting.

CHORUS is interoperable with other public-access delivery solutions, agency search portals, publisher platforms, and scholarly repositories and archives.
