Messages & calendars

Formats for personal information: email messages, calendar events and contact cards. Each is plain text with named fields, so mail, calendar and address book programs can swap them.

One email as sent: header fields, then a body with MIME parts.

.ICS

iCalendar

Calendar events, to-dos and time zones as text content lines.
