Event Reports

CalConnect XXII -- October 3-7 2011

CalConnect Interoperability Test Events - 3-5 October
CalConnect Roundtable Technical Conference - 5-7 October

Current to 26 September 2011
Hotel Meeting Room specified

CalConnect XXII, consisting of a CalConnect Interoperability Test Event, and a CalConnect Roundtable Technical Conference, will be held in Prague, Czech Republic, hosted by Kerio Technologies.

The Interoperability Test Event will take place all day Monday and Tuesday October 3-4, and Wednesday morning October 5, ending at noon. The Roundtable will begin with lunch at 12:00 on Wednesday the 5th, and last through Friday afternoon the 7th.

CalConnect Interoperability Test Event: At this meeting, we hope to offer both a regular CalConnect Interoperability Test Event and a Mobile Calendaring Interoperability Test Event, which will be combined into a single physical event. A participating organization may register for either or both events for a single registration fee, but should be aware that they may require additional individuals to participate in both events (they will take place in parallel).

The Interoperability Test Event is open to both members and non-members as participants or as observers; please see CalConnect Interoperability Test Event October 2011 for current information. Check back periodically as this will be updated as more information becomes available.

You do not need finished or polished code to participate in the IOP testing; in fact as soon as you have something working at all, testing against other participants can help debugging and code development, especially in identifying red herrings and wrong decisions.

Roundtable Technical Conference:

The Roundtable Technical Conference will offer Technical Committee sessions, to which all members and observers are welcome, informal BOFs (Birds of a Feather sessions), plus additional sessions and committee meetings. In addition, workshops/symposia will be offered on Thursday and Friday mornings.

Friday afternoon will be the full Plenary meeting of the Consortium, open to all participants. This session will include report-outs from all Technical Committees, and establishment of future goals and directions for the Consortium.


Please see Registration and Payment Options to choose your registration type and payment option for the Roundtable and/or the CalConnect Interoperability Test Events. Note that you must register separately for the Roundtable and for the Test Events.

Special Registration Fees: For CalConnect XXII, the registration fee for non-members is a single fee of $350 which covers one participant in either the Interoperability Test Event, the Roundtable Technical Conference, or both. You must still execute separate registration forms. For members who are not calendaring vendors, the registration for the Interoperability Test Event is $350 which covers one participant but does not include the Roundtable. In all cases additional participants will be charged the regular fee for additional Test Event participants ($150 each) or Roundtable participants ($350 before 17 Setember, $395 thereafter).


The venue for CalConnect week will be the Conference Hotel, Hotel Majestic Plaza, Stepánská 33, 110 00 Prague 1. Our event will take place in the Majestic II Room. The Interoperability Test Event (Monday, Tuesday, and Wednesday until noon), and the Roundtable, including the Thursday and Friday symposia and workshops, will take place there; the Wednesday reception will also be in the hotel. Monday and Thursday dinners will be off site. See Conference Hotel for more information about the hotel.

Prague is served by Ruzyne, Prague International Airport. Direct connections are available from most European cities and some connections from North America, mostly from the East Coast. Additionally, low-cost airlines such as Easyjet and Ryanair serve Prague from smaller airports in Europe and the U.K.

Ground Transportation: See Public Transit for information about public transportation options. A good alternative is the Airport Express which takes you to the Museum stop on the Metro "C" line, close to the hotel. Taxis are also available for individuals or small groups.

Additionally, the hotel will arrange shuttle service in advance for individuals or small groups from or to the airport at the following rates: Car for max 3-4 people, 680 CZK - $40 USD; Minibus for 8, 1050 CZK - $60 USD; Minibus for 12-15, 1990 CZK - $110 USD. The hotel service must be booked in advance; you will be offered the option to book a transfer from the airport to the hotel as part of your room booking proces, and you may arrange service back to the airport during your stay.
