This property defines whether or not an event is transparent to busy time searches.
IANA and non-standard property parameters can be specified on this property.
This property can be specified once in a "VEVENT" calendar component.
Time Transparency is the characteristic of an event that determines whether it appears to consume time on a calendar. Events that consume actual time for the individual or resource associated with the calendar SHOULD be recorded as OPAQUE, allowing them to be detected by free/busy time searches. Other events, which do not take up the individual's (or resource's) time SHOULD be recorded as TRANSPARENT, making them invisible to free/ busy time searches.
This property is defined by the following notation:
transp = "TRANSP" transparam ":" transvalue CRLF
transparam = *(";" other-param)
transvalue = "OPAQUE" ;Blocks or opaque on busy time searches. / "TRANSPARENT" ;Transparent on busy time searches. ;Default value is OPAQUE Example: The following is an example of this property for an event that is transparent or does not block on free/busy time searches:
