Over Wikidata

Data doneren aan Wikidata
Linked Data - San Francisco

Wikidata is een meertalige opensource database die gelezen en geschreven kan worden door zowel mensen als machines. Het geeft data in alle talen die worden ondersteund door de WikimediaFoundation, en creëert een mogelijkheid gelijk aan Wikimedia Commons voor bestanden. De data op Wikidata wordt bijgehouden en toegevoegd door een (grote) groep vrijwilligers en machines, net zoals op andere Wikimedia projecten zoals Wikipedia.

Wikidata heeft ondertussen miljoenen items, die elk een ding representeert zoals personen, kunstwerken, concepten, of iets dergelijks. Elk item heeft enkele verklaringen die bestaan uit eigenschappen zoals geboortedatum en de waarde die daarbij hoort. Daarnaast kunnen er ook externe bronnen aangehaald worden zoals een VIAF ID.

Wikidata wordt gehost door de Wikimedia Foundation, een nonprofit organisatie die de vrije, meertalige inhoud wil verspreiden en uitbreiden.

Welke data worden gebruikt


Wikidata focust zich op een basislevel van nuttige informatie over de wereld en linkt naar andere bronnen voor specialistische onderwerpen. Bronnen voor data op Wikidata moeten:

  • Betrouwbaar zijn
  • Publiekelijk beschikbaar zijn

De beste manier om uit te vinden welke delen van de data voor Wikidata nuttig zijn, is om de gemeenschap raad te plegen.

Waarom data toevoegen aan Wikidata

Er zijn vele redenen om data aan Wikidata toe te voegen, zoals:


Help meer mensen jouw informatie te delen

Data van Wikidata wordt gebruikt door vele drukbezochte pagina's, waaronder Wikipedia een van de drukbezochtste is met 15 miljard bezoeken per maand.


Verbeter openbare kennis

Wikidata biedt data aan dat naast de Wikimedia projecten ook daarbuiten kan worden gebruikt. Door data toe te voegen aan Wikidata verzeker je jezelf er ook van dat jouw onderwerpen bewaard blijven en up-to-date zijn in alle Wikimedia projecten en talen.


Increase traffic to your website

Anyone looking at Wikidata or other sites that use Wikidata including Wikipedia can see a clickable reference link for the source of the data, making it easy to visit your website.


Make your data more useful for yourself and others

Under Tim Berners-Lee's (the inventor of the World Wide Web) 5-star Open Data plan, making your data available as a spreadsheet is rated as 2 stars, but adding it to Wikidata will rate it as 5 stars, allowing it to benefit from the network effect. By adding data to Wikidata it becomes more useful, you can:

  • Combine it with other data
  • Use Wikidata tools to explore the data
  • Visualise your data along with data from other sources

Organisations who have worked with Wikidata


Case studies

Many organisations are choosing to work with Wikidata. Case studies are available on the following projects:

Wikidata and copyright

Copyright symbol 9.gif

An overview of open data and data licensing is available at Wikidata:Open data publishing.

All data on Wikidata is released under Creative Commons CC0 (public domain). However individual facts and identifiers, such as numbers and IDs are not copyrightable. If you are an institution based in Europe, the whole of your ID list may be under database copyright, but we would not be copying the entire list in bulk; rather, volunteers add most of them individually, one at a time. For more information please see the Wikimedia Foundation’s guidance on database rights.

Every database is different. To define whether your organisation would need to make a license change on your data or if the section of data you would like to make available does not fall under copyright please contact the Wikidata community.

Reusing and combining Wikidata data

There are many tools to manipulate data on Wikidata, for a full list see the Wikidata external tools and the Tools Directory.


Reusing data

It's easy to access data on Wikidata. Data can be reused in Wikimedia projects and beyond, making exciting applications possible.

You can use our data including translated names, birth/death dates and locations, free images, you name it.


Matching your data with other data sets

Many tools exist to augment or cross-check your data with data from other sources. One example is BEACON which can give you a list of your IDs matched against any other we have for the same items, e.g Art UK artists against VIAF. Mix'n'match and OpenRefine can be used to create connections between your database and Wikidata.



Several tools exist to visualise Wikidata data including:

  • Histropedia: uses data from Wikipedia and Wikidata to automatically generate interactive timelines with events linked to Wikipedia articles. Example: The Apollo missions
  • Monumental: a tool that allows you to explore built heritage and learn more about monuments by collating information Wikidata, Wikipedia and Wikimedia Commons. Example: Paris
  • Wikidata Graph Builder: uses data from Wikidata to create graphs of concepts and their related concepts.
  • Wikidata Query Service: A service that offers the ability to run complex queries on items in Wikidata, and related tools e.g. World Heritage sites

How to add data to Wikidata

The process of adding Wikidata can be technically challenging but the Wikidata community is very happy to discuss with you the best approach and offer assistance where needed. The basic process is:

  1. Contact the Wikidata community describing what data you have and would like to include in Wikidata.
  2. Decide with the Wikidata community what data is suitable to import.
  3. Work with the Wikidata community to import the data

1. Contact the Wikidata community

Wikimedia Community Logo.svg

There is a central noticeboard for contacting the Wikidata community called Project chat.

  1. Create your own Wikimedia account (do not use the name of an organisation in the title).
  2. Make sure you are logged in
  3. Go to the Project chat page.
  4. Click the blue Start a new discussion button.
  5. Write a message and make sure to include a title in the title line.
  6. Sign the message by writing ~~~~ at the end of your message.
  7. Click Show preview underneath your message to make sure your message has been written correctly, you will see that your username has appeared where the ~~~~ were added.
  8. Click Save page to post the message.

Users will either reply to your message on the Project chat page or on your userpage which you can access by clicking Talk at the top of the screen next to your username. Please note pages become archived after a short while to make room for new messages, to access old messages go to the Archive index.

You can also use IRC.

2. Decide with the Wikidata community what data to import

Wikidata does not include all data available but just a useful subset. Please refer to our notability criteria for the minimum requirements.

3. Work with the Wikidata community to import the data

There are several ways to add data to Wikidata including


Manual data entry

Everyone can add data to Wikidata by manually adding the data.


Online tools

There are a number of online tools to help with the import of data into Wikidata. Some of them that support specific workflows for data imports are:

  • Mix'n'match contains lists of important concepts from reliable sources and allows to match the names to Wikidata entries with one click. It is possible to get your list included. Read the blogpost about the motivation behind Mix'n'match.
  • The primary sources tool allows for a curation workflow for data donations to Wikidata, where Wikidata editors can review, edit, or reject data offered to the community. It was initially developed for datasets from Freebase, but can be used for any collection of very large non-curated datasets.
  • QuickStatements (Q20084080): allows users to create items and upload lists of statements based on input in tab-separated format exported from spreadsheets
  • fatameh allows users to create fully populated items about scientific papers with one click.

Wikidata API

The Wikidata API is a web service that provides convenient access to wiki features, data, and meta-data over HTTP.



Bots (also known as robots) are tools used to make edits without the necessity of human decision-making. Bots on Wikidata can add interwiki links, labels, descriptions, statements, references, and can even create items, among other things. We also collect hints and inspiration for your own code to import data with a bot.

Other ways organisations can be involved with Wikimedia


There are a number of ways organisations can be involved with Wikimedia including:

  • Making media content available
  • Contributing to Wikipedia articles
