Overview
Wikidata is a collaboratively edited, free knowledge base that acts as a central repository for structured data. It supports Wikimedia projects like Wikipedia, Wiktionary, and others, but also provides data to external sites and services. Wikidata's content is freely licensed, exported in standard formats, and interlinked with other open data sets. The project allows both humans and machines to read and edit its data, fostering a broad range of applications from data visualization to knowledge discovery. Its SPARQL query service facilitates complex data retrieval and analysis. Wikidata welcomes contributions from individuals and organizations and offers tools and resources to help users learn and contribute. It is part of the Wikimedia family and aims to provide open, accessible data to the world.
