CalConnect XXXIII, consisting of a CalConnect Interoperability Test Event and a CalConnect Conference (Members Meeting), will be hosted by 1and1 at its Bucharest office on May 18-22, 2015.

The Interoperability Test Event will take place all day Monday and Tuesday May 18-19, and Wednesday morning May 20, ending at noon. The Conference will begin with lunch at 12:00 on Wednesday May 20, and last through Friday May 22.

An informal Introductory Q & A about CalConnect, intended for first-time attendees, will be scheduled at 11:00 on Wednesday the 20th for first-time attendees.    

  CalConnect Interoperability Test Event:

The Interoperabilty Test Events are open to both members and non-members as participants or as observers; please see Next CalConnect Interoperability Test Event for current information. Check back often as this will be updated as more information becomes available.

Please Note: You do not need finished or polished code to participate in the interoperability 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.

CalConnect Conference XXXIII: The CalConnect Conference will offer a variety of sessions on technical and higher-level topics, informal BOFs (Birds of a Feather sessions), plus additional sessions and committee meetings. All attending member representatives and observers are welcome.

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.
