Calendaring and Scheduling Standards Simplification (calsify) ------------------------------------------------------------- Charter Last Modified: 2006-04-25 Current Status: Active Working Group Chair(s): Eliot Lear Aki Niemi Applications Area Director(s): Ted Hardie Lisa Dusseault Applications Area Advisor: Lisa Dusseault Mailing Lists: General Discussion:ietf-calsify@osafoundation.org To Subscribe: http://lists.osafoundation.org/mailman/listinfo/ietf-calsify Archive: http://lists.osafoundation.org/pipermail/ietf-calsify/ Description of Working Group: The Calendaring and Scheduling standards, defined in RFC's 2445, 2446, and 2447 were released in November 1998, and further described in RFC 3283. They were designed to progress the level of interoperability between dissimilar calendaring and scheduling systems. The Calendaring and Scheduling Core Object Specification, iCalendar, succeeded in establishing itself as the common format for exchanging calendaring information across the Internet. On the other hand, only basic interoperability as been achieved between different scheduling systems. The Calsify working group is chartered to: (1) Publish the interoperability issues that have arisen between calendaring and scheduling systems, as well as document the usage of iCalendar by other specifications. (2) Revise the Calendaring and Scheduling standards to advance the state of interoperable calendaring and scheduling by addressing the published interoperability issues. As far as it is possible, the working group will ensure backwards compatibility with widely deployed implementations and other specifications that use it. (3) Clarify the registration process for iCalendar extensions (i.e., the current core object specification only provides a template to register new properties). (4) Advance the Calendaring and Scheduling standards to Draft Standard. (5) Work on transition (upgrade or versioning) mechanisms for calendar data exchange. Proposing an XML representation or transformation of iCalendar objects is out of the scope of this working group. Goals and Milestones: Jul 2005 Submit draft documenting interoperability issues for use in progressing RFCs to Draft Standard. Done Submit iMIP bis draft 00 Done Submit iCalendar bis draft 00, with formatting changes from RFC2445. Done Submit iTIP bis draft 00 Oct 2005 Submit revised interoperability issues draft version based on WG discussion. Dec 2005 WG decision on what document(s) require transition mechanisms and hopefully rough idea what these will look like (and add new goals if needed) Mar 2006 WG last call on interoperability issues draft. May 2006 Submit interoperability issues document to IESG for Informational RFC. May 2006 Submit version of iCalendar bis draft that addresses known interoperability issues from interop events.
