+This module provides importable constants for namespaces.
+
+To use, add "from case_utils.namespace import *".  Namespace variables starting with "NS_" are imported.  As needs are demonstrated in CASE tooling (both in case_utils and from downstream requests), namespaces will also be imported from rdflib for a consistent "NS_*" spelling.
