related issues.
	My hope is that folk don't go off trying to reinvent the wheel but
will, instead, try to stay as close as possible to iCalendar[1], vCard[2]

note that we have been working on a test-case-based version of iCalendar in RDF:

If there's a clear demand for it we would be interested in doing an XML profile for this work. We're also thinking right now about documentation for it, so suggestions are welcome (we're aware that the documentation isn't sufficient right now).

iCalendar (RFC 2445) isn't suitable for all events, but it is almost sufficient for conferences, cinema listings etc and is used in most personal information management tools, which is why round-tripping from an XML format of icalendar to iCalendar is important (we do this).

and EventsML[3] when they do this. (Note: EventsML is produced by the
IPTC[6], the same folk that maintain the NewsML format.) Also, given the
frequently noted similarities between the Atom API and WebDAV[4], one should
probably give some thought to Linda Dusseault's proposed CalDAV extensions
to WebDav[5].
	My personal belief is that every theater (dance, ballet, music,
movie, etc.) every organization, every municipal, state and federal
government, etc. will one day syndicate detailed information on all of their
public events. This will ensure the widest possible dissemination of event
information -- something which is not the case today.
