help Wikidata FAQ

What is Wikidata used for?

Wikidata is a collaboratively edited knowledge graph containing structured statements about entities and their relationships. It is hosted by the Wikimedia Foundation and supplies data used by Wikipedia and other Wikimedia projects.

How does Wikidata differ from Wikipedia?

Wikipedia articles are primarily written as encyclopedia prose, while Wikidata stores structured facts such as identifiers, dates, locations, and relationships. A Wikidata item can therefore support many language editions of Wikipedia without repeating the same data manually in every article.

What are Wikidata item identifiers used for?

Wikidata entities receive identifiers such as Q42, which refers to Douglas Adams. These stable identifiers let software connect information across Wikipedia, Wikimedia projects, and external datasets.

Can Wikidata represent relationships between people and organizations?

Yes. Its statements can connect a person to occupations, employers, works, locations, and other entities using machine-readable properties. That structure is why developers and researchers use Wikidata for queries and data integration rather than only for reading articles.
