Wikidata er ein nýggj verkætlan hjá Wikimedia Foundation: ein frælsur fleirmálsligur, sekunderur dátugrunnur, grundaður á samstarv, sum savnar struktureraði dáta sum veita stuðul til Wikipedia, Wikimedia Commons, til hinar Wikimedia verkætlanirnar og fleiri aðrar afturat.
Hvat merkir hetta?
Lat okkum hyggja nærri at tí innleiðandi setninginum í smálutum:
- Fræls. Dáturnar í Wikidata eru útgivnar undir einum frælsum lisensi, sum loyvir at dáta hagani kunnu endurnýtast í nógvum ymiskum samanhangum.
- Grundaður á samstarv. Innihaldið í Wikidata er skrivað og viðlíkahildið av Wikidata brúkarum, sum í felag avgera reglurnar fyri upprættan og stýring av innihaldi í Wikidata.
- Fleirmálsligur. Til ber at rætta, leita og endurnýta dáta á fleiri málum. Dáta sum verður inntastað á einum og hvørjum máli, verður beinanvegin atkomiligt á øllum øðrum málum eisini, og víðari rætting á øðrum málum er møguligt og verður eisini eggjað til tað.
- 'Ein sekunderur dátugrunnur. Wikidata skal ikki bara goyma útsøgnir, men eisini keldurnar til hesar og harvið endurspegla margfeldni av tøkari vitan og stuðla týdningin av at útsøgnir kunnu vísast aftur til keldur.
- Innsavnan av struktureraðum dáta. Ólíkt Commons, sum savnar miðlafílur, og Wikipediunum, ið framleiða alfrøðiligar greinar, so savnar Wikidata bert dáta í einum struktureraðum formi. Hetta fer at gera tað lættari hjá Wikimedia verkætlanum og triðja pørtum at endurnýta hesi dáta, og fer at gera tað møguligt hjá teldum at arbeiða við teimum og "skilja" dáturnar.
- Support for Wikimedia wikis. Wikidata assists Wikipedia with more easily maintainable information boxes and links to other languages, thus reducing editing workload while improving quality. Updates in one language are made available to all other languages.
- Anyone in the world. Anyone can use Wikidata for any number of different ways by using its application programming interface.
How does Wikidata work?
Wikidata is a central storage repository that can be accessed by others, such as the wikis maintained by the Wikimedia Foundation. Content loaded dynamically from Wikidata does not need to be maintained in each individual wiki project. For example, statistics, dates, locations, and other common data can be centralized in Wikidata.
The Wikidata repository
The Wikidata repository consists mainly of items, each one having a label, a description and any number of aliases. Items are uniquely identified by a Q followed by a number, such as Douglas Adams (Q42).
Statements describe detailed characteristics of an Item and consist of a property and a value. Properties in Wikidata have a P followed by a number, such as with educated at (P69).
For a person, you can add a property to specify where they were educated, by specifying a value for a school. For buildings, you can assign geographic coordinates properties by specifying longitude and latitude values. Properties can also link to external databases. A property that links an item to an external database, such as an authority control database used by libraries and archives, is called an identifier. Special Sitelinks connect an item to corresponding content on client wikis, such as Wikipedia, Wikibooks or Wikiquote.
All this information can be displayed in any language, even if the data originated in a different language. When accessing these values, client wikis will show the most up-to-date data.
| Item | Property | Value |
|---|---|---|
| Q42 | P69 | Q691283 |
| Douglas Adams | educated at | St John's College |
Working with Wikidata
There are a number of ways to access Wikidata using built-in tools, external tools, or programming interfaces.
- Wikidata Query and Reasonator are some of the popular tools to search for and examine Wikidata items. The tools page has an extensive list of interesting projects to explore.
- Client wikis can access data for their pages using a Lua Scribunto interface. You can retrieve all data independently using the Wikidata API.
Where to get started
The Wikidata tours, designed for new users, are the best place to learn more about Wikidata.
Some links to get started:
- Set your user options, especially the 'Babel' extension, to choose your language preferences
- Help with missing labels and descriptions
- Help with interwiki conflicts and constraint violations
- Improve a random item
- Help translating

Go ahead and start editing. Editing is the best way to learn about the structure and concepts of Wikidata. If you would like to gain understanding of Wikidata's concepts upfront, you may want to have a look at the help pages. If you have questions, please feel free to drop them in the project chat or contact the development team.
There is more to come
Wikidata is an ongoing project that is under active development. More data types as well as extensions will be available in the future. You can find more information about Wikidata and its ongoing development on the Wikidata page on Meta. Subscribe to the Wikidata mailing list to receive up-to-date information about the development and to participate in discussions about the future of the project.
