Abstract
This document describes the various Internet calendaring and
scheduling standards and works in progress, and the relationships
between them. Its intent is to provide a context for these
documents, assist in their understanding, and potentially aid in the
design of standards-based calendaring and scheduling systems. The
standards addressed are RFC 2445 (iCalendar), RFC 2446 (iTIP), and
RFC 2447 (iMIP). The work in progress addressed is "Calendar Access
Protocol" (CAP). This document also describes issues and problems
that are not solved by these protocols, and that could be targets for
future work.

1. Introduction
Calendaring and scheduling protocols are intended to aid individuals
in obtaining calendaring information and scheduling meetings across
the Internet, to aid organizations in providing calendaring
information on the Internet, and to provide for organizations looking
for a calendaring and scheduling solution to deploy internally.
It is the intent of this document to provide a context for these
documents, assist in their understanding, and potentially help in the
design of standards-based calendaring and scheduling systems.
Problems not solved by these protocols, as well as security issues to
be kept in mind, are discussed at the end of the document.
