Group Notes: Extensions to the OWL-Time Ontology — entity relations & temporal aggregates
7 July 2020
<https://www.w3.org/blog/news/archives/8621>
The Spatial Data on the Web Interest Group has published two First Public Interest Group Notes:
<https://www.w3.org/2017/sdwig/>
* Extensions to the OWL-Time Ontology – entity relations
* Extensions to the OWL-Time Ontology – temporal aggregates
OWL-Time [ "owl-time" ] is an ontology for temporal entities and relations between them. OWL-Time defines simple temporal entities (intervals and instants). The "entity relations" note adds four new relations: time:equals, time:hasInside, time:disjoint and time:notDisjoint which complement the original relations and allow for description of more relationships between temporal entities. The "temporal aggregates" note adds one new class time:TemporalAggregate and two properties time:hasPart and its inverse time:isPartof to allow for the description of arbitrary aggregates of temporal entities.
