Another ontology/vocabulary which is centred around events is the CIDOC 
CRM (Conceptual Reference Model). [1]  It is "a formal ontology intended 
to facilitate the integration, mediation and interchange of 
heterogeneous cultural heritage information", and comes out of the 
museums community. There is an OWL representation [2] which has been 
developed by a group at Erlangen-Nuremburg University.  It certainly 
doesn't lack definitions ;-)

I would be interested to hear what Linked Data folks make of it as a 
potential framework for expressing more general event-related 
assertions, i.e. going beyond its stated scope.  I would also value a 
more expert opinion than my own as to whether the current expression of 
the CRM (either the OWL or RDF [3] version) is "fit for purpose" as a 
Linked Data ontology.
