Wikidata is transcluded in other Wikimedia projects in a large variety of ways. For Wikipedia, this can be anything from [[https://en.wikipedia.org/wiki/Template:Infobox_person/Wikidata|determining the values in an infobox]] of an individual's day of birth, day of death, or nationality (quite visible to readers and important to get correct; see [[https://en.wikipedia.org/wiki/Wikipedia:Biographies_of_living_persons|BLP]]) to providing [[https://www.mediawiki.org/wiki/API:Page_info_in_search_results|descriptions that show up only on mobile]] to auto-generating [[https://en.wikipedia.org/wiki/Template:Authority_control|metadata tables]] (e.g., a Library of Congress identifier) that is displayed at the end of the article on desktop to [[https://en.wikipedia.org/wiki/Category:Coordinates_on_Wikidata|simply indicating that Wikidata contains coordinates for a given article even if that article is not using them]].
The goal of this task is to categorize the range of different ways in which Wikidata is transcluded within Wikipedia and begin to identify how to measure the prevalence of each type of transclusion to add more nuance to the counts that can be derived from the `wbc_entity_usage` Mediawiki table. If this initial work goes well, I intend to expand it to Commons and the other projects as well.
 Develop taxonomy of Wikidata transclusion in Wikipedia
 For each type of transclusion, develop method for measuring the prevalence of that transclusion.
 Compare metrics based on `wbc_entity_usage` table to metrics that split out the different types of transclusion.
