2009-07-14. Generate SKOS encoding of vocabulary from Excel spreadsheet.
2009-12-07 SMR Update metadata properties for version, creator, title, and format.
Change skos:HistoryNote to dc:source for information on origin of terms and definitions.
2009-12-07. SMR add collections for mineralogical and sedimentary petrographic categories,
improve annotation and notes on vocabulary. Update metadata properties for version,
creator, title, and format. Change skos:HistoryNote to dc:source for information on

2010-02-13 Add narrower relationship links by adding skos:narrower link in Protege,
defining skos:narrower as inverse of skos:broader, calculating with Pellet reasoner
to add inferred axioms, and using 'file/Export inferred axioms as ontology' in Protege.
2010-11-28 SMR replace URN with http URI according to CGI URI scheme (see https://www.seegrid.csiro.au/wiki/bin/view/CGIModel/PersistentIdentifiersInGeoSciMLServices)
2011-07-01 SMR correct logical inconsistencies in hierarchy; lithostratigraphic is
not subtype of lithologic unit; lithogenetic is subtype of lithostratigraphic. Based
on review comments from OR, Geoscience Australia. Create 201107 version.
2012-02-07 SMR update URI to replace numeric final token with English-language string
as in original URN scheme.
2012-02-27 SMR add exact match triples relating to URIs in 201012 vocabulary scheme

are lower case, remove owl:NamedIndividual and Owl:Thing rdf:types.
2016-07-15 OLR Create new SKOS version
This scheme specifies concepts used to categorize types of Geologic Unit, as defined
by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working
Group. By extension, it includes all concepts in this conceptScheme, as well as concepts
in any previous versions of the scheme. Unit types are differentiated based on their
defining lithological, stratigraphic, or other physical properties.
This file contains the CGI Geologic Unit type vocabulary. Compilation and review in
MS Excel spreadsheet, converted to MS Excel for SKOS generation using GSML_SKOS_fromXLS_2016.02.xslt.
