RE: Event significance and event types(was:Event Significance)

Thanks for this contribution,

I'd like to make a few comments:

It seems to me that the current IPTC taxonomy of "Subjects News Codes" is
already a taxonomy of "event types". When we state that the subject of a news
item is "swimming" we really mean that the subject of this news is an event
related to the act of swimming, ie a swimming event. A subject of "consumer
goods" means an event related to consumer goods. 

Katarina was a "meteorological disaster", which is an existing IPTC news code.
Therefore we (news agencies) are already able to speak about "event types".

The new subject of study among news agencies like AFP and Reuters is the
management of individual entities (eg events) and the creation of news
ontologies, where event types (aka themes) and named entities (people,
organizations, locations events ...) can be interlinked in a semantic network.

But it seems impossible to create a worldwide and market-wide "news ontology" (I
mean the formal expression of classes of concepts and named relationships btw
concepts). As an example, some news organization are interested in parenthood
between people; others want to keep track of "who sleeps with who" ;-) Some
organizations process concepts like people and organizations, others treat
animals as a special class of concept.
What NewsML 2 aims at is offering the plumbing needed by news organizations for
managing and distributing their own formal ontologies.
