1.  Introduction

1.1.  Motivation

   The JSCalendar [draft-ietf-calext-jscalendar] data format is used to
   represent calendar data, and is meant as an alternative to the widely
   deployed iCalendar [RFC5545] data format.

   While new calendaring services and applications might use JSCalendar
   as their main data format to exchange calendaring data, they are
   likely to interoperate with services and clients that just support
   iCalendar.  Similarly, existing calendaring data is stored in
   iCalendar format in databases and other calendar stores, and
   providers and users might want to represent this data also in
   JSCalendar.  Lastly, some implementations might want to preserve
   custom iCalendar properties, that have no equivalent in JSCalendar
   when converting between these formats.

   To facilitate these use cases, this document provides an
   informational guide how to convert JSCalendar data from and to
   iCalendar.

1.2.  Scope and caveats

   JSCalendar and iCalendar have a lot of semantics in common, but they
   are not interchangeable formats:

   o  JSCalendar contains a richer data model to express calendar
      information such as event locations and participants; while future
