    • Notifications

    • Learning Management Systems


  • Traditional email

    • POP

    • IMAP

    • SMTP / eSMTP

Calendaring and scheduling
Calendaring and Scheduling

  • iCalendar from IETF

    • Data format for event data

    • MIME object

    • XML with a DTD, 1-to-1 transformation, less extensible than XML with namespace

Products using icalendar
Products using iCalendar

  • Various Oracle/Corporate Time product lines

  • Lotus Domino and Notes Release Rnext, Organizer

  • Sun Calendar Server Version

  • Exchange, Outlook, Outlook Express

  • MeetingMaker (data import)

  • Apple iCAL currently uses vCalendar


  • A transport independent protocol to transport iCalendar objects

  • iMIP defines email as an iTIP transport

  • iRIP is another iTIP binding or profile

  • ISIP is a proposed binding

Cap calendar access protocol
CAP – Calendar Access Protocol

  • Intended as the protocol between a calendar user agent and a calendar server

  • CAP is a BEEP profile

  • Still in draft, no known implementations, however libical has been planning an implementation

  • BEEP uses SASL / TLS for authentication

  • VSQueries of data on server to create views


  • iCalendar extensions driven by Swedish tourism requirements

    • ‘the 11:00am tour of the castle will be in German but a taped presentation will be available in English’

Oki s c s api

  • Not intended for a server implementation

  • Very simple API that can be used to create a gateway into other C&S systems for simple queries or commitments.

The sip community
The SIP community

  • ISIP - iCalendar SIP-Based Interoperability Protocol

  • The goal of this document is to extend the iCalendar framework so that it can be used to describe Internet multimedia conferences and chat rooms.

  • Discussion about using this as event notification to user’s cell phones.

  • This is an iTIP binding

Mapi providers
MAPI providers

  • Replacement MAPI providers have been used to provide group scheduling in Outlook without and Exchange server

    • Corporate Time’s Outlook Connector

    • Bynari’s Insight Connector

Reservation systems
Reservation Systems

  • Reservation Systems are C&S systems constrained by rule based authorization systems

  • No standard protocols or APIs at this time. Some SIP work is a small subspace of this application domain.
