           JSCalendar: A JSON representation of calendar data
                    draft-ietf-calext-jscalendar-20

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 JSON-based jCal format, it is not a
   direct mapping from iCalendar and expands semantics where
   appropriate.
