Wikidata
Wikidata is Wikipedia's sister project, an open knowledge base holding machine-readable facts about people, organisations and concepts.
Why it matters
Google's Knowledge Panel and many AI systems use Wikidata to recognise organisations; a good item holds founding date, headquarters, website and social accounts in one place.
Rules
Items need verifiable sources and must meet notability criteria; promotional items are deleted.
Frequently asked questions
Can there be a Wikidata item without a Wikipedia article?
Yes, its criteria are broader, but reliable sources are still needed.
