title: Data from: U-Index, a dataset and an impact metric for informatics tools and databases

description: Measuring the usage of informatics resources such as software tools and
 databases is essential to quantifying their impact, value and return on
 investment. We have developed a publicly available dataset of informatics
 resource publications and their citation network, along with an associated
 metric (u-Index) to measure informatics resources’ impact over time. Our
 dataset differentiates the context in which citations occur to distinguish
 between ‘awareness’ and ‘usage’, and uses a citing universe of open access
 publications to derive citation counts for quantifying impact. Resources
 with a high ratio of usage citations to awareness citations are likely to
 be widely used by others and have a high u-Index score. We have
 pre-calculated the u-Index for nearly 100,000 informatics resources. We
 demonstrate how the u-Index can be used to track informatics resource
 impact over time. The method of calculating the u-Index metric, the
 pre-computed u-Index values, and the dataset we compiled to calculate the
 u-Index are publicly available.
