For the German-speaking countries, DBT provides a choice of templates.
German braille is usually contracted. For that purpose, use the template, German - Basic.
German Vollschrift is a system of lightly contracted braille (almost uncontracted). It is rarely used.
German Uncontracted may be used in an educational context.
For all of these templates, the default mathematics code is German Math.
When using German intended for English-speaking countries, one should actually select an English UEB Template and apply the German style on the passages of German text.

German is usually produced in contracted braille. This means that words are not produced in braille on a one-for-one basis. There are abbreviations or contractions in the text. If you have questions about how braille is produced, please contact a member of the relevant braille authority.
Producing this language in uncontracted braille is also quite easy in DBT. Before translation into braille, place the cursor at the top of the document and use the Grade 1 command (Alt+1). When the document is translated, the braille will be uncontracted.
