Abstract
The Calendar Access Protocol (CAP) described in this memo permits a
Calendar User (CU) to utilize a Calendar User Agent (CUA) to access
an iCAL-based Calendar Store (CS). At the time of this writing,
three vendors are implementing CAP, but it has already been
determined that some changes are needed. In order to get
implementation experience, the participants felt that a CAP
specification is needed to preserve many years of work. Many
properties in CAP which have had many years of debate, can be used by
other iCalendar protocols.
