Description

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.

Format Definition

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:

 TRANSP:TRANSPARENT

The following is an example of this property for an event that is opaque or blocks on free/busy time searches:

 TRANSP:OPAQUE
