We are committed to informing the understanding of the research reproducibility and efficiency challenges, using that knowledge as a mechanism of raising awareness, knowledge, and motivation to change practices in the research community.
COS has implemented a sustainability model for maintaining an open-source, public goods infrastructure by partnering with stakeholders in research, including funders, federal agencies, research institutions, and individuals.
As COS has evolved from a small, start-up organization to become an established pillar of the open science movement, we have worked to garner philanthropic support from individuals, particularly researchers, who are similarly committed to supporting free, public, and accessible data.
