DIN 91379

From EverybodyWiki Bios & Wiki



The DIN standard Draft DIN 91379: "Characters and defined character sequences in Unicode for the electronic processing of names and data exchange in Europe, with CD-ROM" [1] defines a normative subset of Unicode Latin characters, sequences of base characters and diacritic signs, and special characters for use in names of persons, legal entities, products, addresses etc. This subset supports all official languages of European Union countries, Iceland, Liechtenstein, Norway, Switzerland and German minority languages. To allow the transliteration of names in other writing systems to the Latin script according to the relevant ISO standards all necessary diacritic signs are provided.

The standard defines a normative mapping of latin letters to base letters A-Z according to the recommendations of ICAO.[2]

In addition to the normative characters the standard defines subsets of extended characters that contain modern Greek letters for Greece and Cyprus, Cyrillic letters for Bulgaria and special characters for names of products and legal entities.

Conforming applications may support additional characters, however for interface agreements or registers it may be appropriate to support only a final subset of characters and sequences based on this standard.[3]

The text of the current standard, de:DIN SPEC 91379, explanations and lists of characters and sequences as Excel and XML files can be found in.[4] This reference contains also an XML schema file with patterns to check conformance of text to subsets defined in this standard. Lists of characters and sequences as plain text files are available in.[5] The draft DIN contains few additional characters and sequences.[1]

To be compliant to this norm, it is required to

  • support all normative letters and sequences at all processing stages,
  • use the encoding UTF-8 at interfaces, and
  • normalize the characters according to Unicode normalization form C (NFC).[1]

The compliance to this standard will be mandatory for German authorities and organisations in the exchange of data between authorities or with citizens and business from Nov 1, 2024.[6]

The architecture guideline for German federal IT demands the usage of this standard. [7]

Current results of the standardization process include the specification DIN SPEC 91379 and the draft DIN 91379. Efforts are being made to further develop it into an European CEN standard.[4]
