Schema.org is a collaborative community that creates, maintains, and promotes schemas for structured data on the internet, in web pages, and in email messages. These vocabularies cover entities, relationships between entities, and actions, and can be extended through a well-documented extension model. As of 2024, over 45 million web domains use Schema.org to markup their web pages with over 450 billion Schema.org objects. (Schema.org)
