           JSCalendar: A JSON representation of calendar data
                    draft-ietf-calext-jscalendar-16

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
   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.
