Online versions

If you just want to have a look at the classification, e.g. to decode a code, the online version of the tabular list of the classification is the right one for you. It corresponds to the printed version in both content and appearance and can be read on the DIMDI website using any standard browser. High link density and integrated code search make navigation easy and comfortable. All online versions are only available in German language.


All download versions are free of charge. In addition to the classification databases, the ZIP files also contain readme files with information about the structure of the databases and download conditions and other important information.

Browser version for local storage

The liable of fees HTML book version (liable of fees) corresponds to the online versions that you can use on the DIMDI website (see above). You can download this version, store it locally and use it in the same way as the online version without being online. DIMDI website search for text in the entire classification is not available for locally stored databases.

Editing and electronic processing

For editing, you require the ODT version. For electronic processing of the data, you need an XML version; metadata and crosswalks are special TXT (CSV) versions. For all formats for electronic processing, the ZIP files also contain additional information from preface and appendix in ODT form (in older versions as RTF).

ODT, PDF and XML formats

ODT (OpenDocument Text) is a LibreOffice format. LibreOffice is an open-source comprehensive office software bundle which uses the OASIS OpenDocument format as the standard storage format. OASIS (Organization for the Advancement of Structured Information Standards) is an international organisation dedicated to the continuing development of web standards and supported by all leading information technology providers. The OpenDocument format was confirmed as ISO standard ISO/IEC 26300 in 2006 and is the document exchange format recommended by the European Commission. More information and the LibreOffice bundle for download is available on the LibreOffice website:

PDF (Portable Document Format) is an open standard (ISO 32000). PDF files contain data from any applications and are platform-independent, i.e. they can be displayed on any computer using a range of free of charge PDF readers.

XML (Extensible Markup Language) is a markup language for the representation of hierarchically structured data in form of text files. The XML-versions of the classifications are based on ClaML (Classification Markup Language), a special XML notation for classifications, established by WHO since 2005 and accepted as European Standard in 2007 (DIN EN 14463:2008-02). The European Standard was replaced by an international standard in 2012 (ISO 13120:2013-11). Same as TXT files, XML files can be read and edited by any editor; however, the use of a specific XML editor is recommended.
