## Definition

Linked data is a method of publishing structured data on the web using URIs and RDF so that entities and their relationships can be interconnected across different data sources. It is the technology underlying the semantic web — enabling machines to follow links between data sets to discover and reason about entity relationships.

## Why It Matters for AI Search

Linked data is the infrastructure that connects an entity's structured data across the web. When a brand's schema markup includes sameAs links to Wikidata and Wikipedia, it is participating in linked data — creating machine-readable connections that AI systems can follow to build a richer, more accurate entity understanding. The sameAs property is the most practical linked data implementation for most brands.
