Wikidata
is a
free
collaborative
multilingual
, secondary knowledge base, collecting structured data to provide support for
Wikipedia
Wikimedia Commons
, the other
wikis
of the
Wikimedia movement
, and to anyone in the world.
What does this mean?
Let's look at the opening statement in more detail:
Free.
The data in Wikidata is published under the
Creative Commons Public Domain Dedication 1.0
, allowing the reuse of the data in many different scenarios. You can copy, modify, distribute and perform the data, even for commercial purposes, without asking for permission.
Collaborative.
Data is entered and maintained by Wikidata editors, who decide on the rules of content creation and management. Automated
bots
also enter data into Wikidata.
Multilingual.
Editing, consuming, browsing, and reusing the data is fully multilingual. Data entered in any language is immediately available in all other languages. Editing in any language is possible and encouraged.
A secondary knowledge base.
Wikidata records not just statements, but also their sources, and connections to other databases. This reflects the diversity of knowledge available and supports the notion of verifiability.
Collecting structured data.
Imposing a high degree of structured organization allows for easy reuse of data by Wikimedia projects and third parties, and enables computers to process and “understand” it.
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 data from Wikidata to build their applications and services.
How does Wikidata work?
This diagram of a
Wikidata item
shows you the most important terms in Wikidata.
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
Items and their data are interconnected.
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
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
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.

retrieve all data programmatically using different APIs and service
Client wikis can access data for their pages using a
Lua Scribunto interface
