  Wikidata is steadily becoming more central to Wikipedia, not just in
maintaining interlanguage links, but in automated population of content within
the articles themselves. It is not well understood, however, how widespread
this transclusion of Wikidata content is within Wikipedia. This work presents a
taxonomy of Wikidata transclusion from the perspective of its potential impact
on readers and an associated in-depth analysis of Wikidata transclusion within
English Wikipedia. It finds that Wikidata transclusion that impacts the content
of Wikipedia articles happens at a much lower rate (5%) than previous
statistics had suggested (61%). Recommendations are made for how to adjust
current tracking mechanisms of Wikidata transclusion to better support metrics
and patrollers in their evaluation of Wikidata transclusion.
