    • Wikidata is a document-oriented database, focused on items. Each item represents a topic (or an administrative page used to maintain Wikipedia) and is identified by a unique number, prefixed with the letter Q— for example, the item for the topic Politics is Q7163. This enables the basic information required to identify the topic the item covers to be translated without favouring any language.

      Information is added to items by creating statements. Statements take the form of key-value pairs, with each statement consisting of a property (the key) and a value linked to the property.

    • QUOTE: Wikidata is a free and open knowledge base that can be read and edited by both humans and machines.

      Wikidata acts as central storage for the structured data of its Wikimedia sister projects including Wikipedia, Wikivoyage, Wikisource, and others.

      Wikidata also provides support to many other sites and services beyond just Wikimedia projects! The content of Wikidata is available under a free license, exported using standard formats, and can be interlinked to other open data sets on the linked data web.

    • Wikidata is a project of the [<tvar|wmf>https://wikimediafoundation.org/</> Wikimedia Foundation]: a free, collaborative, multilingual, secondary database, collecting structured data to provide support for Wikipedia, Wikimedia Commons, the other Wikimedia projects, and well beyond that.
      • Free. The data in Wikidata is published under the [<tvar|1>//creativecommons.org/publicdomain/zero/1.0/</> 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, all without asking permission.
      • Collaborative. The data in Wikidata is entered and maintained by Wikidata editors, who decide on the rules of content creation and management in Wikidata. Template:Ll do also enter data in 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 database. Wikidata can record not just statements, but also their sources, thus reflecting the diversity of knowledge available and supporting the notion of verifiability.
      • Collecting structured data. Unlike Wikimedia Commons, which collects media files, and the Wikipedias, which produce encyclopedic articles, Wikidata will collect data, in a structured form. This will allow easy reuse of that data by Wikimedia projects and third parties, and will enable computers to easily process and “understand” it.
      • Support for Wikimedia projects. Wikidata supports Wikipedia with more easily maintainable language links and infoboxes, thus reducing the workload in Wikipedia and increasing its quality. Improvements or updates in one language are available in all other languages.
