+The TRM_CODESYSTEM_VER table represents a single CodeSystem resource with a specific URL and version. It is used to map terminology concepts represented by various TRM_CONCEPT_* tables to a single CodeSystem resource.
+
+The TRM_CODESYSTEM table represents the canonical representation of a CodeSystem resource with a specific URL and maps to a single TRM_CODESYSTEM_VER row which is treated as the current version of the CodeSystem (i.e. the resource referenced if no version is specified). For example, two CodeSystem resources `CodeSystem/loinc-2.67` and `CodeSystem/loinc-2.68` might have the same CodeSystem.url, e.g. `http://loinc.org` but different CodeSystem.version values. In this case each will each have exactly one row in the TRM_CODESYSTEM_VER table, but there will be only one row in the TRM_CODESYSTEM table which will link only to the more recently updated TRM_CODESYSTEM_VER resource.
