Calendaring Extensions to WebDAV

Described in RFC 4791 since March 2007

Allows clients to access calendaring and scheduling information on a remote server

Based heavily on existing standards such as iCalendar, HTTP and WebDAV



Designed for implementation by any collaborative software that needs to maintain, access or share collections of events

Developed as an open standard to foster interoperability between software from different implementors

Gained industry wide support very rapidly



Large number of servers:

Sun Calendar Server 7

Google and Yahoo Calendar

Oracle

Apple

Growing number of clients:

Mozilla Thunderbird

Apple iCal

Iphone

Evolution


Why is it important for Symbian?

Open platform → open standards

User wants access to own data from different devices without being locked in

Up-to-date data on desktop, mobile and web

Opens a wide range of personal, business and enterprise use case

Bug entry: Add support for external calendars via CalDav

Yes please! this is the main reason why Im selling my g1..

Oh yes! I can not believe that an internet enabled modern Smartphone does not do this. Really, I'm shocked. Fix this, this is ridiculous.

Without this, the calendar is pretty much useless

A modern smartphone should be able to handle external calendars via iCal / CalDAV

I need this feature as well, for both work and private

It's a must-have feature for every business phone. And it's a big disappointment to me that it's not been implemented yet


What exactly is going on?

Development started during the summer

Close cooperation with the Organizer Package owner, Sharad Upadhyay

Planned to be merged for Symbian^3


What exactly is supported?

CalDAV and GroupDAV

Ctag and WebDAV sync extension

Dynamic discovery of server capabilities

Multiple calendars, integration into native calendar, offline use


Interoperability, QA and testing

Ensure high quality and integration with a large number of different servers

Test against many different implementations

writing data: be as compliant as possible

reading data: be as tolerant as possible


Interoperability, QA and testing

Automated test suite

Participated at CalConnect interoperability event at Apple's campus in October 2009


The future - Get involved

Creating and deleting remote calendars

CalDAV Scheduling Extensions to WebDAV

Add invitees to event

Free/Busy lookup

Discovery of CalDAV Push-Notification


The future - Get involved

CardDAV:

vCard Extensions to WebDAV

Open platform – open standard

Stay ahead of the curve
