           JSCalendar: A JSON representation of calendar data
                    draft-ietf-calext-jscalendar-32

Abstract

   This specification defines a data model and JSON representation of
   calendar data that can be used for storage and data exchange in a
   calendaring and scheduling environment.  It aims to be an alternative
   and, over time, successor to the widely deployed iCalendar data
   format, and to be unambiguous, extendable, and simple to process.  In
   contrast to the jCal format, which is also JSON-based, JSCalendar is
   not a direct mapping from iCalendar, but defines the data model
   independently and expands semantics where appropriate.
