Description

An OWL representation of the model for Temporal Hierarchical Ordinal Reference Systems defined in GeoSciML v3, and modeled after ISO 19108.

The THORS ontology introduces the classes thors:Era and thors:eraBoundary which are elements in a thors:ReferenceSystem.

The temporal positions of boundaries, and topological relationships between Eras are aligned to the Allen temporal algebra, as implemented in OWL-Time.

Hierarchical Time Ordinal Reference System^c

IRI	`http://resource.geosciml.org/ontology/timescale/thors#ReferenceSystem`
Is Defined By	http://resource.geosciml.org/ontology/timescale/thors
Description	A temporal ordinal reference system is a constrained temporal topological complex, in which the edges are called 'eras'. Each era may be subdivided into one set of eras of the next finer rank. This constraint is required to establish a mono-hierarchy, so that a set of temporal positions defined relative to the reference system may be uniquely ordered.
