Dear Frans
There is another one on modeling events with particular strength on
supporting various different features of event relations including
causality, correlation and different dimensions of mereology (i.e.,
event composition). The ontology is plainly called 'F' or Event-Model-F
and we have been working on it some time ago. Unfortunately, the website
/ ontologies were down (they used to be included in a Wiki). So, I spend
some time collecting the information and putting the ontologies up again.
- For background information on 'F' please see the papers listed here:
http://www.kd.informatik.uni-kiel.de/en/research/ontologies/ -> then
click on 'Event-Model-F'
- The ontologies themselves are now available from (latest version) this
website:
http://ansgarscherp.net/ontology/events.semantic-multimedia.org/ontology/2010/12/05/
I hope this helps and Merry Christmas,
Ansgar

Hello,
I think I have made some progress in this matter. It was triggered by
a personal message I received in response to my question. It pointed
me at an article about Narrative Knowledge Representation Language
(NKRL), a formal way of describing events. In this article a reference
was made to DOLCE, an upper ontology. This made me realize that the
general thing I was looking for could very well be found in sources of
general semantics: upper ontologies. And indeed that seems to be the
case. In hindsight it makes a lot of sense.
I think I have found applicable properties inDUL (DOLCE+DnS Ultralite)
<http://ontologydesignpatterns.org/wiki/Ontology:DOLCE+DnS_Ultralite>,
UMBEL <http://www.umbel.org/> and CIDOC CRM
<http://www.cidoc-crm.org/> (not really a general ontology, but my
question comes from a cultural heritage use case). Upper ontologies
like these offer semantics for an 'event' concept, various properties
to associate something else with an event, and inverse properties to
link from the event to the thing that undergoes the event. In my case,
I think I will use the following properties to link to an event:
* from DUL:
http://www.ontologydesignpatterns.org/ont/dul/DUL.owl#isParticipantIn
<http://www.ontologydesignpatterns.org/ont/dul/DUL.owl#isParticipantIn>
* from CIDOC-CRM:
http://www.cidoc-crm.org/cidoc-crm/P12i_was_present_at
<http://www.cidoc-crm.org/cidoc-crm/P12i_was_present_at>
* from UMBEL: http://umbel.org/umbel#relatesToEvent
<http://umbel.org/umbel#relatesToEvent>
More suggestions are welcome, but now I at least have something.

Hello,
This is a question about events, something that happens or
happened at some time. I have found several ways of describing
events in Linked Data:
* use The Simple Event Model Ontology
<http://semanticweb.cs.vu.nl/2009/11/sem/semdoc.html>
* use The Event Ontology
<http://motools.sourceforge.net/event/event.html>
* use LODE <http://linkedevents.org/ontology/>
* http://dublincore.org/documents/dcmi-terms/#dcmitype-Event
<http://dublincore.org/documents/dcmi-terms/#dcmitype-Event>
So I won't have trouble describing an event using common
vocabularies. But what is a general way of linking a resource to
an event? Expressing that an event takes place in the course of
life of a resource? Which predicate could I use?
Some background: I am trying to assign certain temporal properties
to resources. Some specific properties can not be found in common
vocabularies. However, those entities can be found in common
SKOS-based thesauri, because SKOS thesauri tend to have more
specialized contents than ontologies.
Take the concept 'pedestrian zone' from EuroVoc
<http://eurovoc.europa.eu/4799> for example: A SKOS concept
exists, but the concept is not readily available as a temporal
property, if for instance one wants to share the fact that a
certain street will be a pedestrian zone at a certain time.
A possible way of using such a term would be to define an event of
which the subject (dcterms:subject
<http://purl.org/dc/terms/subject>) is the SKOS concept. The event
would have applicable start or end times. That way I have a
temporal entity built on common semantics, and I have avoided
having to create my own vocabulary for describing the thing I want
to express. And so I arrive at the problem: I have some data
describing an event, but how can I link from a resource to the
event, with the meaning of 'has undergone event' or 'will undergo
event'?
I see that event ontologies do allow linking from an event to a
place or a person. But I would rather have it the other way
around: link from a resource to an event, instead of linking from
the event. And how would it be possible to link an event to things
that are neither people not locations (e.g. 'life on earth')? I
could be mistaken, but it seems a general property to link to an
event could come in handy.
About six weeks ago have asked this question at
answers.semanticweb.com (here
<http://answers.semanticweb.com/questions/32996/how-to-link-a-resource-to-an-event>),
but so far no reply came in. So I thought I could try to ask the
question on this list now.
Greetings,
Frans
