1. THORS ontology updated to align with OWL-Time (instead of ISO 19108).
2. GTS ontology updated to use sam-lite (instead of OWL implementation of ISO 19156) with a lightweight SOSA alignment
3. Spatial data uses GeoSPARQL (instead of OWL implementation of ISO 19107)
2019-06-10 - This revision adjusts the nomenclature of units to use only chronologic terminology rather than stratigraphic terminology [e.g. Cambrian-Age 2 in place of Cambrian-Stage 2; Cambrian-Epoch 2 in place of Cambrian-Series 2; Early/Late in place of Lower/Upper (namely in application to Epoch/time units rather than their equivalent Series/stratigraphic units—e.g. Early Jurassic Epoch rather than Lower Jurassic Series)]; and the whole artefact is renamed ‘Geologic Time Scale’.
Also: changed samfl:shape --> geo:hasGeometry

RDF representation of the Geologic Time Scale, as defined in the International Chronostratigraphic Chart (ICC) from the International Commission on Stratigraphy (ICS). The ICC embraces both chronostratigraphic (time-rock) units and their equivalent geochronologic (geologic-time) units, the former being related to the ‘Stratigraphic points’ referred to below, and the latter (geochronologic units) being employed in this RDF representation.
