Description

This is an RDF/OWL representation of the GeoSciML Geologic Timescale model, which has been adapted from the model described in Cox, S.J.D, & Richard, S.M. (2005) A formal model for the geologic timescale and GSSP, compatible with geospatial information transfer standards, Geosphere, Geological Society of America 1/3, 119–137.

This ontology (GTS) imports and specializes a generic ontology for Temporal Hierarchical Ordinal Reference System (THORS).

It is recommended that the W3C OWL-Time ontology is used to encode details of temporal positions, and also to record temporal relationships between eras/intervals.
