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.
