# Wikidata

> Wikidata is a free, collaborative knowledge base of machine-readable facts about entities, structured as items with unique IDs (QIDs) and referenced statements. It feeds Google's Knowledge Graph and is one of the sources AI engines lean on to recognize and describe a brand.

Each Wikidata item has a stable identifier (a QID like `Q95`) and statements that connect it to other entities with sourced references. That structure makes its facts easy for machines to extract and trust.

Wikidata maintains its own notability rules, separate from Wikipedia's, so a properly sourced item can exist without a Wikipedia article. For a brand, a clean Wikidata entity is one of the most direct ways to put correct, corroborated facts into the knowledge graph.
