Yup, of course I could also have written [ event:agent :me ; ... ]. Just thought about people who want to transform it into RDF/XML easily. :-)

The Event ontology is of course kind of a simplification of models like ABC Harmony  - although I find their Event / Action differentiation a bit dodgily modelled. I tried mapping those two, GOLD  and SUMO but found SUMO to be even more chaotic. :-D
Anyway, I think this can be approached quite pragmatically, the Event ontology is sufficient for most things, I don't deem the subtle differences necessary here. Nonetheless I'd be interested in David Lewis' work.
