Braille Code Metadata Rules & Terms

Rules for Braille Code Metadata

Braille code metadata terms are presented in the following form:

• Language (Required): This uses two-letter language codes (e.g., en for English, fr for French). If the language has regional distinctions, such as different braille standards in various countries, the regional code is added (e.g., en-GB for British English).
  • Refer to Tags for Identifying Languages for more information
• Script (Optional): If the language uses more than one script, a script tag is added (e.g., Cyrl for Cyrillic, Deva for Devanagari). This ensures clarity in cases like Serbian braille, which can be written in both Latin and Cyrillic scripts.
  • Use ISO 15924 to determine how to script names.
• Braille Code (Required): This identifies the specific braille system in use, such as Unified English Braille (UEB), Nemeth for math, or Bharati for Indian languages.
  • Braille code names should be in English.
• Grade (Required): This specifies the level of contraction or complexity in the braille code, such as grade1 for uncontracted braille and grade2 for contracted braille. If the braille system does not follow a specific grading system, no-grade is used.
  • Grade names are set by how the braille code and grade is colloquially understood by its users. Allowed values are: no-grade, grade0, grade1, grade1.1, grade1.2, grade1.3, grade1.4, grade1.5, grade2, and partial.
• Specialization (Optional): For specialized systems like computer or music braille, an additional tag can be appended (e.g., comp8 for 8-dot computer braille).
  • Acceptable values are: comp8 (8-dot computer braille), comp6 (6-dot computer braille), math, music, and phonetic
