GeologicVocabulary

A collection of terms (ControlledConcepts) and their associated definitions and relationships between the terms, usually organized in some logical fashion such as in a hierarchy (geologic time, rocks, unconsolidated deposits...). An instance of a GeologicConcept may occur only once in a particular GeologicVocabulary. In GeoSciML this is normally identified using a URN in the "classifierScheme" branch of the CGI URN scheme, with the @codesSpace attribute set to "urn:ieft:rfc:2141".
