California Digital Libraries, PLOS, and DataONE are partners in Make Data Count (http://mdc.lagotto.io/), an NSF-funded project to design and develop metrics that track and measure data use, i.e. “data-level metrics” (DLMs). DLMs are a multi-dimensional suite of indicators, measuring the broad range of activity surrounding the reach and use of data as a research output. This report communicates the project progress to date.
