Categories used in english WikipediaI'm interesetd in a deeper understanding of how Wikidata handle wikipedia categories. With a Query like this I can explore categories as they are linked to a specific Wikipedia. Number of categories with a sitelink to "en.wikipedia.org"QUERY REQUEST: I know there are already 4032165 wikimedia categories (executing this query: SELECT (COUNT(?item) AS ?total) WHERE { ?item wdt:P31 wd:Q4167836.} ) but due to sitelinks aren't properties, is complex for me to know which of these are used in english - or spanish or other - Wikipedia. .13:56, 18 January 2018‎ (UTC)) at contribs • talk (Tsaorin comment was added byunsignedThe preceding – Thanks
