RFC2445 Deviations
|
|
====================
|
|
|
|
Most RFC2445 (iCalendar) implementations deviate from the specification in one
|
|
form or another. These deviations may be a result of ambiguous or missing
|
|
requirements, or just poor interpretation of the specification. Below we
|
|
attempt to document known assumptions and deviations for specific RFC2445
|
|
implementations.
|
|
|
|
|
|
MS Outlook:
|
|
|
|
- allows DATE-TIME representation without specifying a VALUE=DATE-TIME
|
|
parameter
|
|
|
|
- Outlook will not read files that don't contain the mandatory UID and
|
|
DTSTAMP properties in VEVENT, etc. components
|
|
|
|
- provides quoted TZID parameters, and as such does not conform with RFC2445
|
|
|
|
- generates additional spaces in recurrence rules containing a BYDAY
|
|
component
|
|
|
|
|
|
Mozilla Calendar/Sunbird:
|
|
|
|
- long content lines are folded with a single LF character (should be CRLF)
|
|
|
|
- folds all property parameters and values
|
|
|
|
- Generates non-standard "X" properties
|
|
|

|
phpicalendar:
|
|
|
|
- long content lines are folded with a single LF character (should be CRLF)
|
|
|
|
|
|
KOrganizer:
|
|
|
|
- long content lines are folded with a single LF character (should be CRLF)
|
|
|
|
- folds all property parameters and values
|
|
|
|
|
|
Apple iCal:
|
|
|
|
- uses VALUE=TEXT on some X-properties (NOTE: this is valid behaviour)
|
|
|
|
- iCal events don't include the mandatory DTSTAMP property
|
|
|
|
- iCal 1.0 doesn't appear to include vtimezone definitions where applicable
|
|
(this appears fixed as of 1.5)
|
|
|
|
|
|
Google Calendar:
|
|
|
|
- Generates DTSTART properties in DATE format without specifying the
|
|
required VALUE=DATE parameter |
