The IETF has published the revision to iTIP

RFC 5546, iCalendar Transport-Independent Interoperability Protocol (iTIP), has been published by the IETF as a Proposed Standard. This is the revision to RFC 2446 (iTIP) which has been underway for some time. RFC 5546 obsoletes RFC 2446. See CalConnect congratulates everyone who was involved in progressing this work.

Nokia Corporation joins CalConnect

I am delighted to announce that Nokia Corporation has joined The Calendaring and Scheduling Consortium.

Reminder: Early Registration for Roundtable XVII ends on 15th

If you are planning to attend Roundtable XVII at UC Irvine, please remember that early registration ends on the 15th and the registration fee will increase, so if you know you are coming, please register before EOB on Friday.

Only 4 weeks to CalConnect XVII

It is now only 4 weeks (28 days) to CalConnect XVII, February 1-5 at the University of California at Irvine, and only 12 days until Early Registration (for the Roundtable) ends on the 15th. After that the registration fee will increase from $350 to $395.

As usual, Monday, Tuesday, and Wednesday morning will be the Interoperability Test Event, while Wednesday afternoon to Friday afternoon will be the Roundtable. Remember you must register separately for the two events.

The logistics page (see below) will be updated shortly with the actual schedule for Technical Committee sessions and with Topical Agendas for the sessions.

This Interoperability Test Event will actually be comprised of both a regular IOP Test Event (we expect to be doing CardDAV testing in addition to iCalendar and CalDAV testing) and a Mobile Calendaring IOP Test Event primarily focused on calendaring via synchronization (ActiveSync and SyncML).

Please see for logistics and planning information, plus registration links. For more information specifically about the Mobile Interop including the testing schedule, see
