This document describes an ontology for publishing descriptions of historical events as Linked Data, and for mapping between other event-related vocabularies and ontologies.
The URI for this vocabulary is
http://linkedevents.org/ontology/
When used in RDF or XML documents the suggested prefix is lode
Each class or property in the vocabulary has a URI constructed by appending a term name to the vocabulary URI. For example:
http://linkedevents.org/ontology/Event
http://linkedevents.org/ontology/atTimeThis vocabulary defines one class and 7 properties .
| Term Name | Type | Definition |
|---|---|---|
| Event | class | "Something that happened," as might be reported in a news article or explained by a historian. |
| atPlace | property | a named or relatively specified place that is where an event happened. |
| atTime | property | an abstract instant or interval of time that is when an event happened. |
| circa | property | an interval of time that can be precisely described using calendar dates and clock times. |
| illustrate | property | an event illustrated by some thing (typically a media object). |
| inSpace | property | an abstract region of space (e.g. a geospatial point or region) that is where an event happened. |
| involved | property | a (physical, social, or mental) object involved in an event. |
| involvedAgent | property | an agent involved in an event. |
Definition: "Something that happened," as might be reported in a news article or explained by a historian.
An event consists of some temporal and spatial boundaries subjectively imposed on the flux of reality or imagination, that we wish to treat as an entity for the purposes of making statements about it. In particular, we may wish to make statements that relate people, places, or things to an event.
Note that, unlike some defintions of "event," this definition does not specify that an event involves a change of state, nor does it attempt to distinguish events from processes or states.
| URI: | http://linkedevents.org/ontology/Event |
|---|---|
| Label: | Event |
| Subclass of: | dctype:Event and crm:E2_Temporal_Entity |
| Equivalent to: | event:Event and dul:Event |
Definition: [The value of this property is] a named or relatively specified place that is where an event happened.
This property relates an event to some meaningful place, which may have a name (e.g. "Paris") or may be defined relative to some other entity or entities (e.g. "the unincorporated area between Carson and Harbor Gateway"). An event may be related to more than one such place.
| URI: | http://linkedevents.org/ontology/atPlace |
|---|---|
| Label: | at place |
| Domain: | Event |
| Range: | dul:Place |
| Subproperty of: | dul:hasLocation |
Definition: [The value of this property is] an abstract instant or interval of time that is when an event happened.
Equivalent definitions from other ontologies: * C4DM Event ontology: "Relates an event to a time object, classifying a time region (either instantaneous or having an extent)."
This property relates an event to some subjectively imposed temporal boundaries, i.e. a span of time. An event can be related to only one such span of time.
| URI: | http://linkedevents.org/ontology/atTime |
|---|---|
| Label: | at time |
| Domain: | Event |
| Range: | time:TemporalEntity |
| Subproperty of: | dul:isObservableAt and crm:P4_has_time-span |
Definition: [The value of this property is] an interval of time that can be precisely described using calendar dates and clock times.
An temporal relation expressing nearness in time.
This property relates a span of time that cannot be precisely located in a chronological series to another span of time that can be precisely located, thus asserting that the latter is an approximation of the former.
| URI: | http://linkedevents.org/ontology/circa |
|---|---|
| Label: | circa |
| Domain: | time:TemporalEntity |
| Range: | time:DateTimeInterval |
Definition: [The value of this property is] an event illustrated by some thing (typically a media object).
This property relates any thing (typically a media object) to an event which it illustrates, documents or comments upon.
| URI: | http://linkedevents.org/ontology/illustrate |
|---|---|
| Label: | illustrate |
| Domain: | owl:Thing |
| Range: | Event |
Definition: [The value of this property is] an abstract region of space (e.g. a geospatial point or region) that is where an event happened.
Note that a statement that relates an event to a region of space using this property only asserts that an event occurred somewhere within the region and does not assert that it occurred everywhere within the region.
This property relates an event to some subjectively imposed spatial boundaries, i.e. a region of space. An event can be related to only one such region of space.
| URI: | http://linkedevents.org/ontology/inSpace |
|---|---|
| Label: | in space |
| Domain: | Event |
| Range: | geo:SpatialThing |
| Subproperty of: | dul:hasRegion |
Definition: [The value of this property is] a (physical, social, or mental) object involved in an event.
This property relates an event to any physical, social, or mental object or substance. It does not imply any causal relationship or influence or any other kind of explanatory relationship such as creation, destruction, etc.
| URI: | http://linkedevents.org/ontology/involved |
|---|---|
| Label: | involved |
| Domain: | Event |
| Range: | dul:Object |
Definition: [The value of this property is] an agent involved in an event.
This property relates an event to anything with agency, such as a (legal or natural) person, a group, an organization, a computational agent, etc. It does not imply any causal relationship, influence, intentionality, etc.
| URI: | http://linkedevents.org/ontology/involvedAgent |
|---|---|
| Label: | involved agent |
| Domain: | Event |
| Range: | dul:Agent |
| Subproperty of: | involved |
