3.5.1. PUBLISH
The "PUBLISH" method in a "VJOURNAL" calendar component has no
associated response. It is simply a posting of an iCalendar object
that may be added to a calendar. It MUST have an "Organizer". It
MUST NOT have "Attendees". The expected usage is for encapsulating
an arbitrary journal entry as an iCalendar object. The "Organizer"
MAY subsequently update (with another "PUBLISH" method) or cancel
(with a "CANCEL" method) a previously published journal entry.
Parameters:
component - one or more component objects
Returns:
a calendar object validated to conform to iTIP method PUBLISH
3.5.2. ADD
The "ADD" method allows the "Organizer" to add one or more new
instances to an existing "VJOURNAL" using a single iTIP message
without having to send the entire "VJOURNAL" with all the existing
instance data, as it would have to do if the "REQUEST" method were
used.
The "UID" must be that of the existing journal entry. If the "UID"
property value in the "ADD" is not found on the recipient's calendar,
then the recipient MAY treat the "ADD" as a "PUBLISH".
When handling an "ADD" message, the "Attendee" treats each component
in the "ADD" message as if it were referenced via an "RDATE" in the
main component. There is no response to the "Organizer".
Parameters:
component - a calendar component to add
Returns:
a calendar object validated to conform to iTIP method ADD
3.5.3. CANCEL
The "CANCEL" method in a "VJOURNAL" calendar component is used to
send a cancellation notice of an existing journal entry. The message
is sent by the "Organizer" of a journal entry. For a recurring
journal entry, either the whole journal entry or instances of a
journal entry may be cancelled. To cancel the complete range of a
recurring journal entry, the "UID" property value for the journal
entry MUST be specified and a "RECURRENCE-ID" property MUST NOT be
specified in the "CANCEL" method. In order to cancel an individual
instance of the journal entry, the "RECURRENCE-ID" property value for
the journal entry MUST be specified in the "CANCEL" method.
There are two options for canceling a sequence of instances of a
recurring "VJOURNAL" calendar component:
a. The "RECURRENCE-ID" property for an instance in the sequence MUST
be specified with the "RANGE" property parameter value of
"THISANDFUTURE" to indicate cancellation of the specified
"VJOURNAL" calendar component and all instances after.
b. Individual recurrence instances may be cancelled by specifying
multiple "VJOURNAL" components each with a "RECURRENCE-ID"
property corresponding to one of the instances to be cancelled.
When a "VJOURNAL" is cancelled, the "SEQUENCE" property value MUST be
incremented as described in Section 2.1.4.
Parameters:
component - one or more component objects
Returns:
a calendar object validated to conform to iTIP method CANCEL
