Raw Material Role
This file contains the CGI Raw Material Role vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. The vocabulary defines concepts for categorizing raw material relationships with Earth Resource occurrences. 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 Raw Material Role vocabulary. Compilation and review in Google doc spreadsheet; adopted June 2013; converted to MS Excel XML for SKOS generation using SKOS_for_GA_from_XLS_2016.03.xslt
