Downloading a current version

Nomenclature is continuously updated, and will no longer have named versions, as the printed volume did. The filename contains a date to help you identify when you last downloaded it. Data model information is provided in the Web Services and Documentation section below. The file will be updated daily

Downloading a conversion file

This file is not needed for new implementations. It may be useful as an interim step for those who previously implemented Nomenclature (e.g. Nomenclature 3.0 or 4.0) in their systems. Since the current version of Nomenclature excludes inverted order for terms made up of single words, this file containing all inverted-order terms (both single- and multiple-word terms) matched to the new Nomenclature IDs may help with conversion from systems that rely on the inverted order. After using this file to add the new Nomenclature IDs to your system, you will be able to use the IDs to update to the current version of Nomenclature.

If you are implementing Nomenclature for the first time, use one of the current versions provided above, instead of this conversion file
