Schema.org
Le vocabulaire universel du web sémantique.
Schema.org provides a collection of shared vocabularies (schemas) that webmasters can use to mark up their pages in ways recognized by major search engines like Google, Bing, and Yahoo. By using these tags, you tell search engines exactly what a page is about—whether it's a person, an event, a product, or a recipe.
