Vocabulary information

Value Qualifier
This file contains the CGI Value Qualifier vocabulary, as defined by the IUGS Commission for Geoscience Information (CGI) Geoscience Terminology Working Group. These terms are taken from the enumeration for values that may be assigned as the valueQualifier on CGI_Value. Definitions are proposed. This codelist includes qualifiers of several sorts: 1. frequence of occurrence--qualifiers that indicate how many occurrences of a described feature are expected to have a reported value. E.g. 'commonly red, sometimes brown'; 2. kinds of statistical procedure used to determine a single value to report based on a collection of observed values, e.g. mean, median, mode.; 3. kinds of nil values; 4. kind of value--a limiting value or the actual estimated value. By extension, this vocabulary includes all concepts in this conceptScheme, as well as concepts in any previous versions of the scheme.

2009-12-07 SMR Update metadata properties for version, creator, title, and format. Change skos:HistoryNote to dc:source for information on origin of terms and definitions.
2010-02-08. SMR Clean up namespace declarations so concept URI's follow CGI URN scheme; concepts have URN, are not document fragments.

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 relate URI for concept in this vocabulary to URI in 201012 vocabulary
