We present tools for reporting and accessing citations to published data sets in the DataONE network of repositories. Make Data Count (https://makedatacount.org) promotes the use of an international set of data usage and citation tracking services that are being provided through Scholix, DataCite, CrossRef, and other community participants. DataONE provides a Data Metrics service that helps repositories report citations and usage counts to the DataCIte Event Data service and to access those for individual data sets as well as arbitrarily structured data collections. These collections might be built for all of the data in a repository, for a thematic or project-based dataset collection that spans repositories, or for institutional collections that span repositories, such as for field stations and marine labs. In addition to the core citation reporting services, DataONE also has developed an R package, scythe (https://github.com/DataONEorg/scythe), for searching full text article sources for data citations, triaging those for false positives, and then reporting them to DataONE and DataCite Event Data. This enables repositories and data providers to close the loop on data citation reporting while publishers improve their reporting to services like Event Data. Scythe is an open source, community maintained tool to help us all better understand the impact of open data.
