The JMdict/EDICT project is a project with the goal of creating a freely-available dictionary database for the Japanese language. It was started in 1991 by Jim Breen.
Another project started in 1991 by Jim Breen is the KANJIDIC project. Similarly to JMdict, it is a project aiming to create a freely-available database. Whereas JMdict is a dictionary for words, KANJIDIC is a dictionary for Kanji.
