  This is the second paper in a series of bibliometric studies of research
data. In this paper, we present an analysis of figshare, one of the largest
multidisciplinary repositories for research materials to date. We analysed the
structure of items archived in figshare, their usage, and their reception in
two altmetrics sources (PlumX and ImpactStory). We found that figshare acts (1)
as a personal repository for yet unpublished materials, (2) as a platform for
newly published research materials, and (3) as an archive for PLOS. Depending
on the function, we found different bibliometric characteristics. Items
archived from PLOS tend to be coming from the natural sciences and are often
unviewed and non-downloaded. Self-archived items, however, come from a variety
of disciplines and exhibit some patterns of higher usage. In the altmetrics
analysis, we found that Twitter was the social media service where research
data gained most attention; generally, research data published in 2014 were
most popular across social media services. PlumX detects considerably more
items in social media and also finds higher altmetric scores than ImpactStory.
