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.

WHAT WE DO

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

HOW WE DO IT

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.

CHORUS INDICES

We have created essential indices to help you navigate today’s publishing landscape.

Funder Open Access / Public Access Plans connects you directly to worldwide funder open access / public access requirements and data management plans.

Publisher Data Availability Policies Index maps the push for transparency, showing how publishers now demand authors share underlying data or explain access barriers.

Software Citation Policies Index tracks how publishers increasingly require proper citation of research software, following FORCE11 guidance.

US Agency Gold Standard Science Plans lists agency plans in response to the OSTP Gold Standard Science guidance.

All provide direct links to original policies and get updated annually.
