Change skos:HistoryNote to dc:source for information on origin of terms and definitions.
2010-02-11 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.
2010-09-26 SMR work on rearranging hierarchy to recognize that the top concept is
'present', all others are entailed by this property. Also recognize inconsistent labeling
of major-minor and dominant-subordinate. Proposal in this is 'more than half', 'less
than half', and change 'dominant' label to 'major' to parallel usage of 'minor'. Awaiting
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)
2011-07-07. GD Clean up remaining namespace declarations so no URN is present in the
ontology. Removed empty concepts with genid.
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 skos:exactMatch relating URI in this vocabulary to URI in 201012
version using numeric tokens. Update the vocabulary definition text.

This file contains the CGI Proportion Term vocabulary, as defined by the IUGS Commission
for Geoscience Information (CGI) Geoscience Terminology Working Group. This vocabulary
provides terms that may be used to qualitatively express abundance of composition
parts in a geologic unit or earth material description. Quantity that specifies the
fraction of the geologic unit composed of the compound material. This vocabulary is
used for GeologicUnit.GeologicUnitPart.proportion, GeologicUnit.compositionPart.proportion,
and for compoundMaterial.ConsituentPart.proportion. By extension, this vocabulary
includes all concepts in this conceptScheme, as well as concepts in any previous versions
of the scheme.
This file contains the 2016 SKOS-RDF version of the CGI Proportion Term vocabulary.
