We have been successfully using Brian Suda's xhtml2vcal.xsl
(available from http://suda.co.uk/projects/X2V/) to transform some
hCalendar embedded in an Atom 1.0 newsfeed to iCalendar format. It
is used as part of a local application for generating newsfeeds
called OXITEMS. After switching from Outlook 2003 to Outlook 2007,
a colleague is reporting a problem with the iCalendar that OXITEMS
is generating.
It appears that if the iCalendar provides an X-WR-CALNAME property,
Outlook 2007 will not import the event(s) into your main Outlook
Calendar but it will create a new calendar with a name that is the
value of the X-WR-CALNAME property.
Currently, xhtml2vcal.xsl always generates an X-WR-CALNAME property
and gives it the value of the title element of the input document
(using an empty string if there is no title element in the input).
We often provide web pages listing events with iCalendar buttons
for each event. The aim is to make it easy for a user to import
details of an event into whatever calendaring system they are
using. It would be silly if the user got a new calendar every time
they clicked on an iCalendar button. The OXITEMS system also has
the ability to send out a message with an iCalendar attachment
whenever an event item is added to a newsfeed. Again it would be
silly if the recipient of this message got a new calendar created
if they opened the attachment.
Here's an analysis of what happens for various calendar clients.
If the X-WR-CALNAME property is present, Outlook 2007 behaves as
follows:
(a) If you open an iCalendar file, Outlook 2007 will create a new
calendar. If you open it again, it will create another new
calendar (with the same name).
(b) If, in Outlook 2007, you explicitly import an iCalendar file,
it will ask you whether you want to create a new calendar or import
the event(s) into your calendar. If you choose the later, it
assumes you only have one calendar even though Outlook 2007 allows
you to create as many calendars as you wish. If instead you choose
"new calendar", it will create a new calendar. If you repeat the
import it will create another new calendar with the same name.
If the X-WR-CALNAME property is absent, Outlook 2007 will import
the event(s) into your main Outlook Calendar.
Google Calendar, Outlook 2003 and WebCalendar ignore the contents
of the
X-WR-CALNAME property if it is present. If you have more than one
calendar, Google Calendar allows you to select the calendar you
want to import into.
With Apple iCal, you get the same behaviour no matter whether there
is an X-WR-CALNAME property or not. iCal asks you whether you want
to import the event(s) into a new calendar or into an existing
calendar and if the latter it asks which one. This happens both
when you double-click an iCalendar file and also when you
explicitly import the file.
I'm trying to work out what to do:
(a) continue as now (always providing an X-WR-CALNAME property)
making it
an inconvenience for Outlook 2007 users;
(b) always omit the X-WR-CALNAME property which, for Outlook 2007,
would
mean that all the events would go into your main calendar which
may
be not what you want;
(c) include the X-WR-CALNAME property only if there is more than one
event in the calendar.
