Innovative applications and contributions from the Wikidata community

Featured WikiProject:
WikiProject COVID-19.

As the world combats the ongoing COVID-19 pandemic, Wikidata has been extremely useful in collecting and modelling useful information related to COVID-19, from relevant research articles and clinical trials, to epidemiological statistics of various regions, to lexemes for words and phrases commonly associated with the pandemic, and much more. A lot of work from WikiProject COVID-19 goes into creating and maintaining these items, bolstering Wikidata's role as a helpful open resource in the pandemic.
