Hi Yves, RaphaŽl,

Yves: how would you see/write an annotation with an event model? Do  
you mean replacing/doubling the ma:relation property by x:hasEvent,  
x:hasTime, x:hasPlace etc? How could we deal with descriptions  
involving multiple places, times and events if we do not integrate  
them in a generic "Event" container, that would bring us back to the  
first issue: how to link a complete graph as an object for a property...

Best,
Vťronique
