I unfortunately haven't yet looked in depth at the existing iCalendar 
documents for three reasons. First, I couldn't find any comprehensive 
document describing the entire iCalendar ontology in RDF. Secondly, my 
foremost concern was vCard; iCalendar is of interest to me only in the 

Mostly importantly is that I decided, because I was creating a 
specification based upon the interrelation among directory, vCard, and 
iCalendar (and this doesn't seem to have been done before), I might as 
well create it from scratch the way (I think) it should be done, and 
then compare notes---which is what I'm doing now.

Taking this comprehensive approach has been productive. For example, 
although iCalendar calls PERIOD a specialized value type (for which 
normally one would create a typed literal), I've found that it is better 
modeled as an RDF class on its own, allowing the icalendar:duration 
property to re-use the iCalendar duration datatype. Another benefit has 
been the recognition that UTC-OFFSET is inconsistent between vCard and 
iCalendar; I've chosen the vCard syntax, as it more closely follows

By the way, where is this iCalendar schema that I keep seeing mention of?
