2009-07-14. Generate SKOS encoding of vocabulary from Excel spreadsheet.
2010 11 27 SMR convert identifiers from URN to http URI according to CGI URI scheme.
2010-02-08. SMR Clean up namespace declarations so concept URI's follow CGI URN scheme;
concepts have URN, are not document fragments.
2010-02-12 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.
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
to number-token URIs in 201012 version of same concepts.
2012-11-24 SMR Update to 201211 version; add collection entity, check all pref labels
are lower case, remove owl:NamedIndividual and Owl:Thing rdf:types.
2016-06-15 OLR - reformat Excel spreadsheet to work with XSLT, to make consistent
SKOS-RDF with all CGI vocabularies. Removed "method unknown" - should use generic
OGC nil values for unknown values. Generated new SKOS-RDF file.
This scheme specifies concepts used to describe the method used to determine the planar
or linear orientation of a GeologicFeature (eg, the dip of a fault), 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. Designed for use in the determinationMethod
property in GeoSciML GSML_PlanarOrientation and GSML_LinearOrientation elements.
This file contains the 2016 SKOS-RDF version of the CGI Orientation Determination
Method vocabulary. Compilation and review in MS Excel spreadsheet, converted to MS
Excel for SKOS generation using GSML_SKOS_fromXLS_2016.01.xslt.
