Structure explanation

Features of the NDLSH vocabulary:

• ID: identifier
• Subject Heading (At least one Yomi is required to accompany with a heading)
• See Reference: Used For (At least one Yomi is required to accompany with a see reference.)
• BT: broader terms
• NT: narrower terms
• RT: related terms
• SA: see also
• SN: scope notes
• NDC(9): NDC (Nippon decimal Classification) term(s) related to the NDLSH term
• NDLC: NDLC(National Diet Library Classification) term(s) related to the NDLSH term

The vocabulary also encode some pronunciation-related information. A single Kanji character has several pronunciations in Japanese. Yomi indicates pronunciation information expressed in syllabic / phonetic characters (Hiragana, Katakana or Roman Alphabet). In the case of NDLSH, pronunciation information is expressed in Katakana. E.g. Kanji character “東” （means east） has two pronunciations “higashi”and “azuma”. Each of the pronunciations is expressed in three types of syllabic characters:

• pronunciation 1
  • ひがし (in Hiragana)
  • ヒガシ (in Katakana)
  • higashi (in Roman Alphabet)
• pronunciation 2
  • あずま (in Hiragana)
  • アズマ (in Katakana)
  • azuma (in Roman Alphabet)

The indexing and sorting of headings and references are determined by the order of these yomi. For this reason, headings, see references and BT/NT/RT references always appear with their yomi.
