Schema.org is a collaborative, community activity with a mission to create, maintain, and promote schemas for structured data on the Internet, on web pages, in email messages, and beyond. Founded by Google, Microsoft, Yahoo and Yandex, Schema vocabularies are developed by an open community process, and through GitHub.
A shared vocabulary makes it easier for webmasters and developers to decide on a schema and get the maximum benefit for their efforts. It is in this spirit that the founders, together with the larger community have come together - to provide a shared collection of schemas.
Rich Snippets (also known as "Rich Results") are normal Google search results with additional data displayed. This extra data is usually pulled from Structured Data found in a page's HTML.
