Wikidata:Wikidata at the 34th Chaos Communication Congress

As usual, the Wikidata team and community will be present at the 34C3 (Q45799888) (Leipzig (Q2079), 27-30 December 2017). Here's a page summarizing all the information if you want to find us there.

Where to find us?

Follow the rocket to find us!

In the hall 2 the following organizations will share an assembly:

When you're in hall 2, find the Jugendhackt/Wikimedia Deutchland assembly (on C3nav). We're located behind the cube with a rocket. The assembly is organized like a flat: you can meet people in the living-room, and the workshops will take place in the Eßzimmer (kitchen).

Who is there?

If you're a Wikidata editor (or developing a tool built on Wikidata, reusing data, building queries...) and attending the Congress, feel free to add yourself there. Let's meet and chat!

What about the questions?

Maybe you found one of our stickers with a weird question on it. Well, now it's time for the answers.

These questions are actually queries, created in SPARQL with the Query Service. The answer is a list of results based on the data existing in Wikidata. Click on "edit the query" on the bottom left corner of the screen to see the query. You can modify the existing queries and build your own!

Please note that the lists can contain errors or be incomplete. That's because Wikidata is a community-driven wiki, and some information may be missing... Good news: you can help improving the content! If you see something incorrect or missing, feel free to edit the related items or create new ones. Have a look at the introduction to Wikidata to learn more. If you have any questions, feel free to come to us, or let a message on the Project Chat.
