Welcome to Wikidata, Circeus!

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, don't hesitate to ask on Project chat. 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) 11:50, 24 August 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) 11:50, 24 August 2013 (UTC)

Bibliothèque municipale de Saint-MalachieEdit

C'est la bibliothèque (en tant qu'institution) ou le bâtiment qui date de 1917? L'usage de inception (P571) n'est pas du tout clair. D'ailleurs je ne sais pas à qu'elle date la bibliothèque J.-A.-Kirouac a été fondée [1]. --Fralambert (talk) 00:05, 28 March 2019 (UTC)

@Fralambert: Le problème n'a rien a voir avec l'idée que "L'usage de inception (P571) n'est pas du tout clair". Le problème est que la bibliothèque en tant qu'institution et le bâtiment sont deux entités différentes pour Wikidata, et sont censés constituer des items séparés: par ex. Grande Bibliothèque (Q3114903) et Bibliothèque et Archives nationales du Québec (Q39628). Vu comme ça, il n'y pas la moindre confusion puisque les deux usages de inception (P571) sont supposés se retrouver sur des items différents de toute façon. (Et en effet, cette confusion se retrouve sur beaucoup d'item, par ex Bibliothèque Gabrielle-Roy (Q2901285), quoique dans ce cas-là, l'un ne prédate pas l'autre.)

Hello. Why I still get allowed qualifiers constraint (Q21510851) when I am using together with (P1706) as a qualifier for qualifies for event (P3085)? [2] Xaris333 (talk) 17:55, 20 May 2019 (UTC)

@xaris333: I do not know how the constraint checking system functions, so I really wouldn't be able to tell you. maybe Wikidata:WikiProject property constraints can, but I have no idea if there's any activity over there at all. Circeus (talk) 20:08, 20 May 2019 (UTC)

VIAF deprecated rankEdit

The problem with deprecating a VIAF value is that VIAF periodically merges duplicates. When this happens, we have bots that update the links, and we could end up with the only remaining value being the deprecated one. We cannot predict which VIAF value will become the primary one, and sometimes VIAF will merge two items and create an entirely new value instead of using either of the previous ones. --EncycloPetey (talk) 14:57, 30 July 2019 (UTC)

@EncycloPetey: Maybe, but right now, that particular value is clearly not the main one. Circeus (talk) 18:24, 30 July 2019 (UTC)
