  abstract = {We argue that an ontology of historical events is needed
in semantic portals for cultural heritage due to three reasons.
First, ontological identifiers (URIs) of events, such as the World War II or 
coronation of Napoleon, are needed 
in order to make collection metadata mutually interoperable in terms of related events---in the vein as identifiers are needed for identifying artifact types, persons,
and geolocations when annotating collection items.
Second, events are of central importance in creating
semantic links between cultural contents in applications such as recommendation systems.
Third, historical events are important as content items of their own,
forming the backbone of chronological histories.}
