If we ever want to improve our situation with dictionaries, it would be good to know:

  • How many different dictionary formats there are
  • Which ones different major projects use
  • What dictionaries exist in each
  • Who knows about their copyright status
To be included in the source tree, and therefore in builds shipped by Mozilla, a dictionary needs to have a licence compatible with the MPL 2.0. Examples of compatible licensing schemes include:
  • MPL 2.0
  • MPL 1.1/LGPL 2.1/GPL 2.0 tri-licence (the old Mozilla licence)
  • Apache 2.0
  • BSD or MIT-style licences
  • LGPL
  • Public domain
Use of some of these licences may require an addition of some text to about:licence. Please file a mozilla.org::Licensing bug when including a new dictionary so the licensing team can check this.

Czech

The only open Czech dictionary I know is [Ispell] that was coverted by OOo guys to [MySpell]. Both dictionaries are under GPL/LGPL. However the original Ispell is kind of abandoned and its author doesn't communicate at all. Therefore, our efforts with relicencing failed. --User:Pawell

Update 2017: With l10n.cz We are trying to find open data for a new dictionary. So far we have found only data under viral copyleft licenses, so we would end up in the same situation we are now, only the dictionary quality would be slightly better. --User:mstanke

Danish

An old danish dictionary is available as aspell/ispell/myspell under GPL2. This is used in the add-on on AMO (Used because Thunderbird 2 does not support hunspell).

A newer dictionary is available as hunspell under the MPL/GPL/LGPL tri-license. It is part of the Danish build starting at Firefox 3.5. Bug 422162

British English [en-GB]

The [British English dictionary] is released under the LGPL.

Dutch

The dutch dictionary is available as Hunspell. The project purposely wants to be very open, such that the list can be used anywhere. Therefore, it is available under BSD and CC-by.

German

Unfortunately cannot ship with Firefox, only as add-ons (German, extended for Austria, variant for Switzerland), as we are using the same as LibreOffice, which is the igerman98 dictionary from Björn Jacke, licensed under GPL v2/v3 and the OASIS distribution license agreement.

Hebrew

OpenOffice.org has a localized version in hebrew, that uses the Hspell format, which is similar to MySpell. They converted it to MySpell for use with mozilla, and it's available here. the MySpell format is GPL, and i think Hspell too. Tsahi

Hungarian

There are new MySpell (Firefox 2) and Hunspell (Firefox 3) add-ons on the Hungarian spelling dictionary site. Unfortunately, Hungarian add-on 1.1.3 of Mozilla Add-on site is bad, see Bug 412386. Hunspell dictionary is licensed under MPL, so we would like it, as default spelling dictionary of the Hungarian localized versions of Mozilla products: Bug 414344.

Vietnamese

There's currently an Aspell dictionary for Vietnamese that is licensed under the LGPL. [2] I've been contacted by someone creating a spellchecker for a Vietnamese distribution of OpenOffice.org (Hunspell?). A demo of that spellchecker is available. [3] I haven't tried either, but I'd imagine creating a Vietnamese spell checker is a bit more straightforward than an English one, say. – Minh Nguyễn (talk, contribs) 01:25, 7 June 2007 (PDT)

There's now a Hunspell dictionary for Vietnamese, licensed under GPL v3. – Minh Nguyễn (talk, contribs) 16:36, 21 May 2008 (PDT)

I've packaged the dictionary as an extension, Vietnamese Dictionary. – Minh Nguyễn (talk, contribs) 22:51, 17 June 2008 (PDT)
The Hunspell dictionaries are now bundled with the Vietnamese localizations of Firefox 3.5 and above and Thunderbird 3.0 and above. – Minh Nguyễn (talk, contribs) 02:16, 5 July 2009 (UTC)

The Vietnamese Hunspell dictionary project has moved from Google Code to GitHub. – Minh Nguyễn (talk, contribs) 04:21, 10 November 2014 (PST)

The dictionary has been removed from the Vietname repository (see bug 1912392). As stated at the top of the page, dictionaries released under GPL are not suitable.

Walloon (wa)

There is a Walloon dictionaries being enriched; it's main target is aspell, but myspell is easily built from it (there is a "make myspell" rule); also a rule to make an XPI for firefox; and a (quite rude) rule to make a myspell for OOo (copying the files to local directory tree, ouch :) )

It can be downloaded on http://chanae.walon.org/walon/aspell.php license is LGPL. -- Srtxg
