change note
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)
2009-05-01 Introduced Holocene subdivisions, as shown in 2018 version from stratigraphy.org - see
2017-02-22 Added additional collections for eras of each rank;
classified rank-based collections using XKOS;
cleaned out legacy Base* instances that did not have links;
renamed *[GS]SP individuals to *SP;
removed all boundaries as TopConcepts, leaving on PreCambrian and Phanerozoic as TopConcepts
2017/02 - Paleogene: Base of Chattian: The numeric age is updated to that at the ratified GSSP (27.82 Ma; Nanno et al. exp. 2017; by request of Simonetti Monechi)
2018-09-27 fixed some broken namespaces and prefixes, mostly related to SPARQL - some kind of search/replace error
2019-05-01 - Updated to 2018-08 version;
removed StratigraphicPoints, Ranks, TimePositions collections;
nested sub-collections in GeochronologicEra
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
Added informal definition of chronometric temporal reference system - Millions of years, counting backwards from 1950

dcterms description 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.
