NMBGMR Draft Geologic Data Model - v. 1.0.3
Attributes: Coded Value Domains

revised: 01-Mar-2012

Attributes used in the NMBGMR Geologic Data Model are a mixture of defined vocabularies in coded value domains, range domains, and user-entered terms. This page shows the coded value domains (CVDs) used by the data model. Values within [square brackets] indicate the actual code stored to aid attribution of values. Addtional entries should be made to the domains as needed.
