Data from Wikidata can be directly displayed on Wikimedia projects, with different methods. With the parser function or Lua code, it is possible to display labels, descriptions, values, references, and a lot of other information stored on Wikidata. For an overview of uses on Wikidata on Wikimedia projects see Wikidata:Wikidata in Wikimedia projects.

On this page, you will learn how to use Wikidata data on your wiki. You can also learn more about what is Wikidata, how the information is organized, or browse the glossary.

Can I access Wikidata data from my wiki?Edit

The two main client functionalities, parser function and access via Lua, can be enabled together on the wikis of the Wikimedia projects. This is the case for almost all Wikimedia projects now.

To check if these functionalities are activated on a wiki, you can access the page Special:Version. In the section "Parser function hooks", if "statements" appears in the list, that means that you can use it on this wiki.

The access to Wikidata data is currently restricted to the Wikimedia projects, because of technical limitations. If you have your own instance of MediaWiki, you can't use Wikidata's data using these features. However, you can set up your own Wikibase instance and use data from there in the same way.

Parser functionEdit

The first way to access data is to use the #statements parser function. This function will allow you to display the value of any statement included in an item.

Direct accessEdit

On a page that is connected to a Wikidata item via the interwiki links, you can use the function by adding the label of the property you want in your language or the P-number of the property. The code has to be added in the wikicode.

Examples:

  • {{#statements:member of political party}} or {{#statements:P102}} will return the "member of political party" value.
  • {{#statements:discoverer or inventor}} or {{#statements:P61}} will return the "discoverer or inventor" value.
  • On w:en:Douglas Adams, the code {{#statements:country of citizenship}} will display "United Kingdom".

Arbitrary accessEdit

You can also display data from an item that is not connected via an interwiki link. For this, you use the same function, adding a parameter from= followed by the Q-id of the item.

Examples:

  • {{#statements:birth name|from=Q42}} will display "Douglas Noël Adams"
  • {{#statements:country of citizenship|from=Q42}} will display "United Kingdom".
  • {{#statements:P1476|from=Q191380}} will display "Notre-Dame de Paris"
  • {{#statements:author|from=Q191380}} will display "Victor Hugo"
  • {{#statements:publication date|from=Q191380}} will display "14 January 1831"

Multiple valuesEdit

When a statements has multiple values, the parser function will show the "best" value, which means:

Example: {{#statements:occupation|from=Q42}} displays "playwright, screenwriter, novelist, children's writer, science fiction writer, comedian, writer" (there are other occupations in Douglas Adams (Q42) but only some are preferred)

Formatted valuesEdit

For some properties, the #statements parser function will display the value in a specific format.

Commons images

The parser function displays a thumbnail preview of the image, resizing it to 200 pixels. It links to the Wikimedia Commons file description page.

{{#statements:image|from=Q42}} displays

 


Geo coordinates

The parser function displays the coordinates in degree-minute-second format.

{{#statements:coordinate location|from=Q243}} displays 48°51′30″N 2°17′40″E

Monolingual text

The parser function displays the string, annotated with the language.

{{#statements:motto text|from=Q95}} displays "Do the right thing".

Date

The date value will be formatted in day-month-year format.

{{#statements:date of birth|from=Q42}} displays 11 March 1952

Links

The links are clickable.

{{#statements:official website|from=Q243}} displays http://www.toureiffel.paris, https://www.toureiffel.paris/en

External IDs

An external ID will provide a direct link to the external website.

{{#statements:IMDb ID|from=Q42}} displays nm0010930

Items

Raw valueEdit

To display the unlinked value, use #property.

Sample:

{{#property:IMDb ID|from=Q42}} displays nm0010930

ModulesEdit

Data can also be accessed with Lua modules, which are much more flexible. Modules that access data from Wikidata should be organized as instance of Wikimedia module using Wikidata (Q59259626). For instance, Module:Wikidata (Q12069631) is available on many wikis, see w:Module:Wikidata#Usage for usage instruction. If your wiki does not contain a module you can copy it from another wiki and add documentation.

For a full technical reference of Lua functions for accessing Wikidata, see mw:Extension:Wikibase Client/Lua.

TemplatesEdit

Some templates use modules to access Wikidata data. They are as simple to use as regular templates. Moreover, using Wikidata, some parameters become unnecessary. For instance, some infoboxes are able to retrieve data from Wikidata, so you just have to insert the template and all the data will magically appear (if the needed information is present on the Wikidata item, of course). For templates using Wikidata see Category:Templates using data from Wikidata (Q11985372).

If you want to create a template on your wiki, check your documentation page about Module:Wikidata and already existing templates.

ListsEdit

Regularly updated listsEdit

Daily updated lists based on SPARQL queries can be configured using Template:Wikidata list (Q19860885). Content is replaced daily.

There are essentially two uses:

  • Work lists: lists with topics to be covered in project namespace. Results can be limited to topics that don't exist.
  • Reference list: lists for a specific topic in article namespace.

This is currently the most efficient way of doing lists.

Dynamic listsEdit

Content is displayed from various items based on a selection done in a Lua module.

Manual listsEdit

A series of items are selected and their properties displayed in an article. Content from Wikidata can be completed with locally edited text.

Examples of use casesEdit

Magic infoboxEdit

CommonsEdit

Commons creator template uses Wikidata with arbitrary access to provide information about the creators of the works.

How to find help ?Edit

You will find contributors on the Wikidata project chat which exists in different languages. Moreover, some wikis have projects dedicated to Wikidata : see Project:WikiProject Wikidata (Q20855878).
