                draft-ietf-calext-eventpub-extensions-11

Abstract

   This specification updates RFC5545 by introducing a number of new
   iCalendar properties and components which are of particular use for
   event publishers and in social networking.

   This specification also defines a new STRUCTURED-DATA property for
   iCalendar RFC5545 to allow for data that is directly pertinent to an
   event or task to be included with the calendar data.
