Glossary of abbreviations and acronyms

This index was compiled to the best of our knowledge, but it cannot guarantee completeness and correctness. Any liability is excluded in the case of incorrect data. Numerous abbreviations/acronyms may have multiple meanings, which are indicated wherever possible. Indicated organisations do not necessarily still exist: they may have disassembled or been renamed. Slightly different terms having the same meaning are marked by “/”. If you find mistakes or incomplete information, please inform us at <post(at)dgk.badw.de>. We thank you for your cooperation.
