A few of the schema structures used by Gmail differ from the
schema.org standard vocabulary. Google has worked with
the schema.org community to standardize its mail-related schemas so that
other email services and email clients can also take full advantage of them.
They have also been deeply integrated with numerous other improvements
at schema.org.
Google remains committed to updating its support of the schemas as adopted
at schema.org. When this process is complete, Google will try to make any
necessary transition as smooth as possible for all developers using these
schemas as well as for their users.
