ELECTRONIC DICTIONARY RESEARCH AND DEVELOPMENT GROUP
====================================================
Source: https://www.edrdg.org/edrdg/licence.html
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.
* **JMDICT** - Japanese-Multilingual Dictionary File - the Japanese and English components (the translational equivalents in other languages, e.g. German, French, Dutch, etc. are covered by separate copyright held by the compilers of that material.)
* **EDICT** - Japanese-English Electronic DICTionary File
* **ENAMDICT** - Japanese Names File
* **COMPDIC** - Japanese-English Computing and Telecommunications Terminology File
* **KANJIDIC2** - File of Information about the Kanji in JIS X 0208, JIS X 0212 and JIS X 0213 in XML format.
* **KANJIDIC** - File of Information about the 6,355 Kanji in the JIS X 0208 Standard _(special conditions apply)_
* **KANJD212** - File of Information about the 5,801 Supplementary Kanji in the JIS X 0212 Standard
* **EDICT-R** - romanized version of the EDICT file. (NB: this file has been withdrawn from circulation, and all sites carrying it are requested to remove their copies.)
* **RADKFILE/KRADFILE** - files relating to the decomposition of the 6,355 kanji in JIS X 0208 into their visible components.
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**
[](https://creativecommons.org/licenses/by-sa/3.0/)
The dictionary files are made available under a Creative Commons Attribution-ShareAlike Licence (V3.0). The Licence Deed can be viewed [here,](https://creativecommons.org/licenses/by-sa/3.0/) and the full Licence Code is [here.](https://creativecommons.org/licenses/by-sa/3.0/legalcode)
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:
1. 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;
2. 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](https://www.edrdg.org/wiki/index.php/JMdict-EDICT_Dictionary_Project)
* [http://www.edrdg.org/wiki/index.php/KANJIDIC\_Project](https://www.edrdg.org/wiki/index.php/KANJIDIC_Project)
See [this page](sample.html) 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.
Where use of the files results in a financial return to the user, it is suggested that the user make a donation to the Group to assist with the continued development of the files. 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.
NB: No contract or agreement needs to be signed in order to use the files. By using the files, the user implicitly undertakes to abide by the conditions of this licence.
**4\. Warranty and Liability**
While every effort has been made to ensure the accuracy of the information in the files, it is possible that errors may still be included. The files are made available without any warranty whatsoever as to their accuracy or suitability for a particular application.
Any individual or organization making use of the files must agree:
2. to assume all liability for the use or misuse of the files, and must agree not to hold the Group liable for any actions or events resulting from use of the files.
3. to refrain from bringing action or suit or claim against the Group or any of the Group's members on the basis of the use of the files, or any information included in the files.
4. to indemnify the Group or its members in the case of action by a third party on the basis of the use of the files, or any information included in the files.
**5\. Copyright**
Every effort has been made in the compilation of these files to ensure that the copyright of other compilers of dictionaries and lexicographic material has not been infringed. The Group asserts its intention to rectify immediately any breach of copyright brought to its attention.
Any individual or organization in possession of copies of the files, upon becoming aware that a possible copyright infringement may be present in the files, must undertake to contact the Group immediately with details of the possible infringement.
**6\. Prior Permission**
All permissions for use of the files granted by James William Breen prior to March 2000 will be honoured and maintained, however the placing of the KANJD212 and EDICTH files under the GNU GPL has been withdrawn as of 25 March 2000.
**7\. Special Conditions for the KANJIDIC, KANJD212 and KANJIDIC2 Files**
In addition to licensing arrangements described above, the following additional conditions apply to the KANJIDIC, KANJD212 and KANJIDIC2 files.
The following people have granted permission for material for which they hold copyright to be included in the files, and distributed under the above conditions, while retaining their copyright over that material:

paragraphs.
Nara Institute of Science and Technology (NAIST),
the copyright holders, disclaims all warranties with regard to this
software, including all implied warranties of merchantability and
fitness, in no event shall NAIST be liable for
any special, indirect or consequential damages or any damages
whatsoever resulting from loss of use, data or profits, whether in an

of or in connection with the use or performance of this software.
A large portion of the dictionary entries
originate from ICOT Free Software. The following conditions for ICOT
Free Software applies to the current dictionary as well.
Each User may also freely distribute the Program, whether in its
original form or modified, to any third party or parties, PROVIDED
that the provisions of Section 3 ("NO WARRANTY") will ALWAYS appear
on, or be attached to, the Program, which is distributed substantially
in the same form as set out herein and that such intended
distribution, if actually made, will neither violate or otherwise
contravene any of the laws and regulations of the countries having
jurisdiction over the User or the intended distribution itself.
NO WARRANTY
The program was produced on an experimental basis in the course of the
research and development conducted during the project and is provided
to users as so produced on an experimental basis. Accordingly, the
program is provided without any warranty whatsoever, whether express,
implied, statutory or otherwise. The term "warranty" used herein
includes, but is not limited to, any warranty of the quality,
performance, merchantability and fitness for a particular purpose of
the program and the nonexistence of any infringement or violation of
any right of any third party.
Each user of the program will agree and understand, and be deemed to
have agreed and understood, that there is no warranty whatsoever for
the program and, accordingly, the entire risk arising from or
otherwise connected with the program is assumed by the user.
Therefore, neither ICOT, the copyright holder, or any other
organization that participated in or was otherwise related to the
development of the program and their respective officials, directors,
officers and other employees shall be held liable for any and all
damages, including, without limitation, general, special, incidental
and consequential damages, arising out of or otherwise in connection
with the use or inability to use the program or any product, material
or result produced or otherwise obtained by using the program,
regardless of whether they have been advised of, or otherwise had
knowledge of, the possibility of such damages at any time during the
project or thereafter. Each user will be deemed to have agreed to the
foregoing by his or her commencement of use of the program. The term
"use" as used herein includes, but is not limited to, the use,
modification, copying and distribution of the program and the
production of secondary products from the program.
In the case where the program, whether in its original form or
modified, was distributed or delivered to or received by a user from
any person, organization or entity other than ICOT, unless it makes or
grants independently of ICOT any specific warranty to the user in
writing, such person, organization or entity, will also be exempted
from and not be held liable to the user for any such damages as noted
above as far as the program is concerned.
