2010-02-11 Add narrower relationship links by adding skos:narrower link in Protege,

to make version 201202
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 triples to map URIs for concepts in this vocabulary

This scheme specifies concepts that describe the geometry or form of a geologic unit,
as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology
Working Group. Examples include: dike (dyke), cone, fan, sheet, etc. Morphology is
independent of the material that composes the geologic unit. 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 Geologic Unit Morphology vocabulary.
