EDICT
JMdict is a large machine-readable multilingual Japanese dictionary. As of August 2013, it contained Japanese–English translations for more than 170,000 entries, representing around 200,000 unique headword–reading combinations. Because the dictionary files are free to use (with attribution), they have been widely adopted on the Internet and are used in many computer and smartphone applications. This project is considered a standard Japanese–English reference on the Internet and is used by the Unihan Database and several other Japanese–English projects.
History
The JMdict/EDICT project was started by Jim Breen in 1991 with the creation of "EDICT" (a flat-text file in EUC-JP encoding), which was later expanded to a UTF-8-encoded XML file in 1999 as "JMdict". The XML format allows for multiple surface forms of lexemes and multiple readings, as well as cross-references and annotations. It permits glosses in other languages and contains French, German, Russian, etc. translations for many entries. The original EDICT format is still being generated for systems that rely on that format.
