Notes

UMDNS is maintained in Apelon’s TDE tool, and is submitted in "ontylog" xml format. The file processed for UMD2012 was "2011NLM_v5.xml".
The information provided here applies explicitly to the English version of UMDNS. The German translation of UMDNS, DMDUMD, was last updated in 1996, and much of the information on this page is not applicable.
