ISSUE-65: General purpose temporal predicates

generic predicates

General purpose temporal predicates

State:
CLOSED
Product:
Time ontology in OWL
Raised by:
Simon Cox
Opened on:
2016-05-18
Description:
The Time ontology is concerned only with formalizing temporal intervals and instants, and does not include any predicates to tie temporal objects to spatial entities or features, or other things. The editors note that predicates that concern temporal behaviour and properties will usually be part of an application or associated with a community of practice.

Nevertheless, there may be some generic predicates that could be conveniently provided as part of the generic time ontology, such as 'validTime'.

Some of these properties may already exist in the ontology (before, after, hasEnd, hasBeginning) but their rdfs:domain is :TemporalEntity, so this would need to be generalized to avoid inappropriate entailments. See https://www.w3.org/2015/spatial/track/issues/64

Else predicates with similar names could be provided for linking to other entities.

Related notes:

The question in my mind is whether the entailment of "is-also-a temporal entity" is problematic or appropriate in the sense that adding "hasDuration" or "inTimePosition" properties has the effect of adding temporality to an entity such as a spatialthing or geometry. I am trying this out in a "module" of geo -> http://geosemweb.org/stgeo. It still allows defining subproperties such as validTime or making a feature slice or sample a temporal entiity.
