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.
OPEN RESEARCH PRINCIPLES
Open research is concerned with making scientific research more transparent, more collaborative and more efficient. Other aspects are more open forms of collaboration and engagement with a wider audience. The following principles were set forth by CHORUS in support of open research.
