Wikidata makes amazing applications possible. In this panel we will hear from different projects using Wikidata's data for social good. They range from citizen participation, to fact checking to understanding the non-profit landscape better.
Jan has been a Wikimedian since 2006. Nowadays, his majority of edits is on Wikidata, but he contributes to Wikimedia Commons and Swedish Wikipedia a lot too. He is active in a number of WikiProjects and is a member of bunch of User Groups and Chapters. Besides the editing, he does a podcast about Wikipedia and sometimes also live streams when he edits.
Lydia Pintscher is the Portfolio Lead for Wikidata. She works at Wikimedia Deutschland and has supported the Wikidata Community since the beginning of Wikidata. In her free time she contributes to KDE, a free software community, as the vice-president of KDE e.V.
Jona is interested in the nonprofit world and in data, so it makes sense he focuses on nonprofit data. He does this on Wikidata and through his own platform, cividata.org. There you can get a clear picture of the nonprofit sector in different countries, including financial info and ways to contact the NGOs. It makes it easy to grasp the sector and use the data as a base for more research and studies.
