Introduction to CalConnect

CalConnect, the Calendaring and Scheduling Consortium, is focused on the interoperable exchange of calendaring and scheduling information between dissimilar programs, platforms, and technologies. Our mission is to promote general understanding of and provide mechanisms to allow interoperable calendaring and scheduling methodologies, tools and applications to enter the mainstream of computing. An overview presentation is available at this link: CalConnect, Calendaring Interoperability and Calendaring Standards. A review of Calendaring standards and standards-related activities to date may be found here: Calendaring Standards.

CalConnect's major activities are:
  • Promote calendaring and scheduling to the information technology industry and the general public
  • Promote and support collaboration between CalConnect members to achieve and improve interoperability
  • Conduct Interoperability Test Events where vendors may bring candidate applications and products and determine their degree of conformance and implementation of relevant calendaring and scheduling standards
  • Promote design and implementation of open calendaring and scheduling standards
  • Develop calendaring and scheduling specifications and publish them or submit them to standards bodies such as the IETF for progression into standards
  • Organize and conduct Technical Committees, CalConnect Conferences, and other CalConnect activities in pursuit of its goals
The Calendaring and Scheduling Consortium was incorporated in the State of California as a California Nonprofit Mutual Benefit Corporation at the beginning of 2004, and is recognized as a 501(C)6 tax-exempt mutual benefit association by the Federal government.


Under the auspices of the IETF (Internet Engineering Task Force) significant work has been done on Calendaring and Scheduling standards in recent years. The Calendaring and Scheduling Consortium will build upon this work extending existing specifications and developing new ones, conducting interoperability testing, and by promoting the widespread adoption and implementation of these and future Calendaring and Scheduling standards and the general acceptance and use of interoperable Calendaring and Scheduling among the internet-using community.


Membership in CalConnecct is open to any organization interested in furthering the goals of the Consortium upon submission and acceptance of a membership application and payment of the appropriate dues. The Consortium invites members from
  • Producers and vendors of Calendaring and Scheduling applications, products and services
  • Open source organizations interested in Calendaring and Scheduling implementations
  • Academic Institutions
  • Customers interested in Calendaring and Scheduling and interested in supporting the goals of the Consortium and influencing the direction of technology evolution
  • Standards-setting organizations
  • Interested individuals

Steering Committee and Technical Committees

The technical affairs and direction of the Consortium will be directed by a Steering Committee made up of representatives chosen from Consortium members. In addition, the Consortium will establish Technical Committees as necessary, open to all members of the Consortium and headed by chairs from Consortium members. Technical Committees will have a well-focused charter and a specific timeframe in which to accomplish their work.

CalConnect Events

CalConnect holds three CalConnect events or "CalConnect weeks" per year, generally at the end of January, May, and September. These events consist of an Interoperability Test Event for the first 2.5 days, followed by a CalConnect Conference the remainder of the week. The CalConnect Conference is where CalConnect Technical Committees hold in-person sessions on ongoing work and report on work to day, together with other scheduled events such as workshops and BOFs.

Work Products

Work in progress is restricted to CalConnect members. However, all completed work products are intended to be publicly and freely available and posted on the CalConnect website or submitted to standards bodies for further progression.

Standards Setting

CalConnect is not itself a formal Standards Settingt Organization in that it does not actuallly publish standards. CalConnect does develop specifications and protocols in its domain, which may either be published by CalConnect as experimental protocols, or submitted to an actual SSO such as the IETF or OASIS for further progression and to become a standard.
