Welcome to CalConnect

Welcome to CalConnectSM, The Calendaring and Scheduling Consortium.

You don't need to be a member of CalConnect to implement a standard. You need to be a member of CalConnect to influence a standard.
We are a non-profit partnership between vendors of calendaring and scheduling systems and tools, and users of those tools. Our purpose is to improve all aspects of calendaring and scheduling, in particular interoperability. We do this by improving existing standards, developing new standards, offering interoperability testing for calendaring and scheduling systems and tools, collaborating with other organizations with similar goals, and conducting periodic conferences where engineers and customers meet and interact in a collegial atmosphere. Although CalConnect is not a formal standards development organization, virtually every important calendaring or calendaring-related standard over the last five years has been authored, edited and/or coedited by members of a CalConnect Technical Committee.

We invite you to learn more about CalConnect, and we hope you will become a participating member. If you have any questions, please use the contact form, or e-mail us directly at contact@calconnect.org.

Please note: CalConnect is in transition to a new web site. The transition will take place over the first part of 2016. All access to "www.calconnect.org" will go to the new site. However some functions and services will require accessing pages on the old website at "calconnect.org" during the transition process. The banner at the top of each page on the old website has been modified to include a notice that this is the old site and to provide a link to the new site. If for any reason you find yourself here on the old site, you may click here to go to the new website.

Our apologies for any inconvenience caused during this transition. If you encounter any problems please e-mail contact@calconnect.org with details.

Coming Events
  • CalConnect XXXVI – Apr 18-22 2016, hosted by Ribose and OGCIO, Cyberport, Hong Kong
  • CalConnect XXXVII – Sep 12-16 2016, hosted by SmoothSync, Dresden, Germany
  • CalConnect XXXVIII – Winter 2017, TBD
  • CalConnect XXXIX – May 2017, hosted by Tandem, Seattle, Washington
Each CalConnect Event consists of an Interoperability Test Event and a CalConnect Conference plus optional events such as Public Days and Seminars.

What we are working on now – major projects underway in CalConnect Technical Committees – become a member and help make these things happen
  • Abstract Calendaring API - We need a full "CRUD" (Create/Read/Update/Delete) Abstract Application Programming Interface and Calendaring Architecture for Calendaring and Scheduling
  • Autodiscovery - One-stop setup for devices and new service providers for calendaring, e-mail, etc. based on internet standard protocols
  • CalDAV Alarms - Extend alarm support to allow for cross-device dismissal, proximity triggers based on location, default alarms in CalDAV
  • CalDAV Attachments - Extends the calendaring server to manage attachments
  • Calendars and Contacts Sharing - Sharing calendars and contacts between users across systems
  • CalWS-REST and CalWS-SOAP - We need to (finally) provide platform and system-independent calendaring and scheduling operations APIs for web services - it's long past time
  • Consensus Scheduling (VPOLL) - TimeTrade, Doodle, Youcanbook.me do it, it should be interoperable - scheduling driven by the attendees who get to vote on the best times and locations for group events
  • Developer's Guides - Create a "cookbook" guide and other supporting materials for iCalendar and potentially other APIs such as CalDAV.
  • Event Publishing Extensions - Calendaring standards need to support the rich environment of Web 2.0 (and beyond) for the publication of public events - rich text, participants and image support
  • iSCHEDULE - We need server to server scheduling between dissimilar systems - we have had client to server scheduling for a long time
  • Non-Gregorian Calendars - Establish a way for recurrences to work with non-Gregorian calendar systems, in particular lunar/solar calendars
  • OASIS WS-Calendar - Working with OASIS to develop their new WS-Calendar standard (scheduling for the Smart Grid), based on xCal, CalWS-REST and CalWS-SOAP
  • PUSH for CalCAV (and CardDAV) - Extend CalDAV and CardDAV with standardized support for PUSH notifications
  • Tasks (VTODOs) - Extend the functionality of VTODOs to support needs such as project management, smart power grids and business task scheduling.
  • Timezone service and registry - Full timezone support via dynamic server calls rather than embedding timezone information in events - no more having event times wrong when timezones change and your software isn't updated
  • VAVAILABILITY - New iCalendar component to describe availability, to 'condition' freebusy lookup and scheduling (e.g. you may be 'free' at 3 a.m. but you aren't available for a meeting)
  • vCard Resources - Define the vCard representation of calendaring resources to ease the discovery and scheduling of resources between any calendar client and server.
