Google Schemas are metadata schemas that are added to emails, allowing contextual information to be displayed in Gmail, Google Searches, and Google Now. The schemas provide a context based on the categorized schema definitions from schema.org, which potentially also allow the emails to be contextually represented in other search engines and products, not just by Google.
The way that the schemas are used by a product can vary from providing a summary of an email, to allowing users to reply to emails with customized actions, or even to collating schema-enhanced emails to provide an overall picture of upcoming activities in a users life.
