Abstract: The Public Library of Science (PLO S) first began to offer Article-Level Metrics (ALM )— including online usage, citations, and altmetrics—in 2009 to provide the research community with a view into the reach of our papers. Since 2009, the data sources in the PLOS suite, have experienced an upsurge and we have more ways to capture engagement with research outputs and more providers operating in this space than ever before. As a result, the existing landscape of ALMs and altmetrics is increasingly difficult to manage, understand, and navigate.To chart a future course for altmetrics, we need to organize the myriad metrics and make them trustworthy for all possible uses in research assessment. One important aspect of this is our ability to establish thoughtful and meaningful ways of grouping similar altmetrics together and distinguishing them from other altmetrics with different meaning. The original groupings established in 2009 were no longer supporting the breadth of metrics now offered and were not in synch with those from other altmetrics providers who have since emerged. We embarked on a process of reconstructing specifications for groupings, which, broadly speaking, were made up of three overall components: evaluation, classification, and implementation.
