This paper presents the purpose, process, and difficulty of constructing the Iroha-Jiruisho Database (DB), which is now partly published, and describes the general prospects of the DB, which consists of words from old Japanese dictionaries. The following are the DB guidelines.
【Overall guidelines】Users can search for words in the Iroha-Jiruisho DB with Chinese characters or kana. Both traditional and new forms are available, as are the traditional and modern kana.
【guideline i】New character forms, which are invisible in the manuscript and search results, are available to use for searching. Further, the forms similar to them in the manuscript will be displayed in the search results.
【guideline ii】Users can search for words using the syllabary spelling of the manuscript, modern kana, and, for native Japanese words, traditional kana.
【guideline iii】In consideration of the owner of the manuscripts, the search results show individual words in the DB, instead of the whole transliteration, for the time being.
