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 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
