If you think about the obvious properties an event has - e.g. time  
and location - it appears there are no single one or combination of  
them could act as a natural inverse functional property.  
Nevertheless, for certain subsets of the class of events, IFPs can be  
found:

* For things like concerts, a property :ticket with  
rdfs:domain :Event and rdfs:range :Ticket is an IFP.

* For events representing, say, checkins to a subversion repository,  
each checkin is given a unique, sequential identifier which, when  
combined with the address of the repository acts as an identifier.
