CHANGE NOTE
2009-07-14: Generate SKOS encoding of vocabulary from Excel spreadsheet.
2009-12-07: SMR add collections for mineralogical and sedimentary petrographic categories, improve annotation and notes on vocabulary.
2010-02-08: SMR Clean up namespace declarations so concept URI's follow CGI URN scheme; concepts have URN, are not document fragments.
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.
2010-11-27: SMR replace URN with http URI according to CGI URI scheme; update version number to 201211
2011-07-07: GD update the class/object properties, define topConcepts properties and inverse.
2012-02-07: SMR update URI to replace numeric final token with English-language string as in original URN scheme.
2012-02-08: SMR add owl:sameAs links to URI's using numeric values. URIs have same prefix (e.g. http://resource.geosciml.org/classifier/cgi/compositioncategory/, but numeric final values.)
2012-11-05: SMR remove named individual, extra owl:thing declarations, add skos:collection
2016-06-15: OLR - redo Excel spreadsheet to work with XSLT, to make consistent SKOS-RDF with all CGI vocabularies. Generate new SKOS-RDF file.
EDITORIAL NOTE
This file contains the 2016 SKOS-RDF version of the CGI Composition Category vocabulary. Compilation and review in MS Excel spreadsheet, converted to MS Excel for SKOS generation using GSML_SKOS_fromXLS_2016.01.xslt.
