There’s more to research than citations: Understanding knowledge-sharing practices with Open Science Indicators - The Official PLOS Blog

"And yet for many years we lacked rigorous, accessible tools for monitoring the growth and impact of open science practices at scale. This was the driving force behind our decision to develop Open Science Indicators (OSIs). While we designed OSIs with our own goals for open science enablement in mind,we knew that others faced similar challenges. By sharing our learnings publicly and being open to community input, we assumed we could help other related efforts. 

After many new developments, collaborations, and feedback from diverse stakeholders, OSIs are becoming a valuable resource for the wider scholarly community. We’ve just released our latest update in partnership with DataSeer which now includes over 166,000 article records from PLOS and a range of comparator journals. The latest release offers full integration of indicators for protocols and study registration as well as a new method for preprint detection. For those who haven’t yet explored the data, or are considering open science monitoring solutions of your own, we want to share what we’ve learned and the possibilities for the future...."
