+This library provides supporting constants and functions for generating deterministic UUIDs (version 5) for UCO Hash and Facet nodes.
+
+There are two general patterns implemented:
+
+1. Some objects are "wholly specified" by their properties.  The leading example of this is uco-types:Hash, which has only the properties hashMethod and hashValue, and both are required to be provided in order to be conformant with UCO.  The function `hash_method_value_uuid` implements a scheme to generate UUIDs for uco-types:Hash nodes based on this pattern.
+2. A pattern based on inherence generates UUIDv5s based on how an inherent object (a.k.a. UcoInherentCharacterizationThing) structurally relates to the object in which it inheres.  For instance, a Facet is understood to only relate to its UcoObject by linking with the uco-core:hasFacet property.  So, a Facet's UUID is determined uniquely by (1) the "UUID namespace" of its corresponding UcoObject, and (2) its OWL Class.
+   A. The term "UUID namespace" is described in RFC 4122 Section 4.3 [#rfc4122s43]_ , and is not intended be confused with `rdflib.term.Namespace`.  For any uco-core:UcoThing (or even owl:Thing), the function `inherence_uuid` defines the procedure for either extracting or generating a UUID for use as a namespace.
+
+This module is independent of, and complements, `case_utils.local_uuid`, which provides deterministic UUIDs based on calling process's environment.
