This property defines the iCalendar object method associated with the calendar object.
IANA and non-standard property parameters can be specified on this property.
This property can be specified once in an iCalendar object.
When used in a MIME message entity, the value of this property MUST be the same as the Content-Type "method" parameter value. If either the "METHOD" property or the Content-Type "method" parameter is specified, then the other MUST also be specified.
No methods are defined by this specification. This is the subject of other specifications, such as the iCalendar Transport- independent Interoperability Protocol (iTIP) defined by [2446bis].
If this property is not present in the iCalendar object, then a scheduling transaction MUST NOT be assumed. In such cases, the iCalendar object is merely being used to transport a snapshot of
some calendar information; without the intention of conveying a scheduling semantic.
This property is defined by the following notation:
method = "METHOD" metparam ":" metvalue CRLF
metparam = *(";" other-param)
metvalue = iana-token
The following is a hypothetical example of this property to convey that the iCalendar object is a scheduling request:
