Learn how to use the schema.org Drupal module to enable rich snippets on your Drupal 7. Download the module from drupal.org/project/schemaorg
The person, event and recipe types from schema.org are known to work at the moment, but there are probably more types that are working. Feel free to experiment and report back at drupal.org/project/issues/schemaorg
Update: The mapping for "name" which is shown at 1min40s is now automatically set for you and is no longer shown in the UI.
