Re: How can I link a resource to an event?

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 in DUL (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
   - from CIDOC-CRM: http://www.cidoc-crm.org/cidoc-crm/P12i_was_present_at
   - from UMBEL: http://umbel.org/umbel#relatesToEvent

More suggestions are welcome, but now I at least have something.

Regards,
Frans
