Welcome to the Wikimedia Hackathon "Data Challenge" a set of SPARQL tasks that should be completed within one and a half hours by teams of two-three people. The event starts at 19:00 UTC and the questions will be made available here at that time.
The answers should be one SPARQL query per question and must be sent to Abbe98(Abbe98 on Telegram) before 21:00 UTC, include the short links to the queries as well as the usernames of your team members. You can do the questions in any order you want and even skip some. Your answers will be graded on a scale of 0-5 based on, does it work, precision (how well does the query answer the question), performance (time to execute), and elegance.
The results will be announced on #wikimedia-hackathon (IRC) and Wikimedia Hackathon (Telegram) later this weekend. Do you have questions about this challenge our are you looking for a team? Let us know in one of the channels above or reach out to one of the organizers (User:Abbe98, User:Ainali, User:VIGNERON, and User:Fuzheado).
