Logo of Wikidata

Welcome to Wikidata, Physikerwelt!

Wikidata is a free knowledge base that you can edit! It can be read and edited by humans and machines alike and you can go to any item page now and add to this ever-growing database!

Need some help getting started? Here are some pages you can familiarize yourself with:

  • Introduction – An introduction to the project.
  • Wikidata tours – Interactive tutorials to show you how Wikidata works.
  • Community portal – The portal for community members.
  • User options – including the 'Babel' extension, to set your language preferences.
  • Contents – The main help page for editing and using the site.
  • Project chat – Discussions about the project.
  • Tools – A collection of user-developed tools to allow for easier completion of some tasks.

Please remember to sign your messages on talk pages by typing four tildes (~~~~); this will automatically insert your username and the date.

If you have any questions, please ask me on my talk page. If you want to try out editing, you can use the sandbox to try. Once again, welcome, and I hope you quickly feel comfortable here, and become an active editor for Wikidata.

Best regards! --Tobias1984 (talk) 13:12, 11 December 2013 (UTC)


Babel lets you view and edit more than one language on Wikidata. Just add e.g. {{#babel:de-N|en-3|es-1|fr-2|nl-3|it-4|da-0}} to your user page. With the same language codes you can add links to your userpage on Wikipedia e.g. de:User:User123. --Tobias1984 (talk) 13:12, 11 December 2013 (UTC)

Sites XML sampleEdit

To import from an XML file into the sites table, see: https://gist.github.com/filbertkm/0254b6fc417ae12bc1b1

Alternatively, you can use a JSON "cache" file to define sites, see docs/sitescache.txt. Specifying a manually written JSON file in $wgSitesCacheFile should just work.


Hi, do I understand it right that this item was created before Property:P3285 was available and is no longer needed anymore? Danmichaelo (talk) 09:08, 18 August 2017 (UTC)
