ELECTRONIC DICTIONARY RESEARCH AND DEVELOPMENT GROUP

GENERAL DICTIONARY LICENCE STATEMENT

1. Introduction

In March 2000, James William Breen assigned ownership of the copyright of the dictionary files assembled, coordinated and edited by him to the The Electronic Dictionary Research and Development Group, then at Monash University (hereafter "the Group"), on the understanding that the Group will foster the development of the dictionary files, and will utilize all monies received for use of the files for the further development of the files, and for research into computer lexicography and electronic dictionaries.

This document outlines the licence arrangement put in place by The Group for usage of the files. It replaces all previous copyright and licence statements applying to the files.

2. Application

This licence statement and copyright notice applies to the following dictionary files, the associated documentation files, and any data files which are derived from them.

ENAMDICT - Japanese Names File

Copyright over the documents covered by this statement is held by James William BREEN and The Electronic Dictionary Research and Development Group.

3. Licence Conditions

The dictionary files are made available under a Creative Commons Attribution-ShareAlike Licence (V3.0). The Licence Deed can be viewed here, and the full Licence Code is here.

In summary (extract from the Licence Deed):

You are free:

to Share - to copy, distribute and transmit the work
to Remix - to adapt the work

Under the following conditions:

Attribution. You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work).
Share Alike. If you alter, transform, or build upon this work, you may distribute the resulting work only under the same, similar or a compatible licence.

For attribution of these files, you must:

in the case of publishing significant extracts of the files, or material based on significant extracts of the files, e.g. in a published dictionary or in vocabulary lists, clearly acknowledge that you used the files for this purpose;
in the case of a software package, WWW server, smartphone app, etc. which uses the files or incorporates data from the files, you must:
1. acknowledge the usage and source of the files in the documentation, publicity material, WWW site of the package/server, etc.;
2. provide copies of the documentation and licence files (in the case of software packages). Where the application packaging does not provide for the inclusion of such files (e.g. with iPhone applications), it is sufficient to provide links, as per the next point;
3. provide links to either local copies of the documentation and licence files or to the locations of the files at Monash University or at the EDRDG site.
  
  If a WWW server is providing a dictionary function or an on-screen display of words from the files, the acknowledgement must be made on each screen display, e.g. in the form of a message at the foot of the screen or page. If, however, material from the files is mixed with information from other sources, it is sufficient to provide a general acknowledgement of the sources as described above.
  
  For smartphone and tablet apps, acknowledgement must be made, e.g. on a separate screen accessed from a menu, such as one labelled "About", "Sources", etc. It is not sufficient just to mention it on a start-up/launch page of the app.
  
  For the EDICT, JMdict and KANJIDIC files, the following URLs may be used or quoted:
  - http://www.edrdg.org/wiki/index.php/JMdict-EDICT_Dictionary_Project
  - http://www.edrdg.org/wiki/index.php/KANJIDIC_Project

See this page for samples of possible acknowledgement text.

Note that in all cases, the addition of material to the files or to extracts from the files does not remove or in any way diminish the Group's copyright over the files. Users of material from the files must NOT claim copyright over that material.

Note also that provided the conditions above are met, there is NO restriction placed on commercial use of the files. The files can be bundled with software and sold for whatever the developer wants to charge. Software using these files does not have to be under any form of open-source licence.

The only method currently available is to make a donation via PayPal using a credit or debit card. Simply click on the following button and follow the instructions.
