fcitx-table-extra for Debian ---------------------------- There are several data files in this source package, the license of them might be something confusing many people. These data files were having their patents, but they were either released by the original author (and the patent holder) into Public Domain (Cangjie), or the patents had expired for several years. We are providing clean-room re-generated data files using their ideas (which is not copyrightable, and obviously not infringing expired patents). * Array*: released to public domain by original authoer - Ref (Chinese): http://www.array.com.tw/BOX/BOX5.htm * Boshiamy: 122588, expected to be expired in 2003, but actually expired in 1992 because of not paying patent fees for more than six months. - Ref (Chinese): http://terryhung.pixnet.net/blog/post/24973556 * Cangjie*: 027984, expired in 1989, released to public domain by original author in 1982. - Ref (Chinese): http://cbflabs.com/?id=12 * Easy: GPL-2+, also referenced in debian/copyright - Ref (Chinese): http://homepage.mac.com/eshen/ez/ezgpl.html * Jyutping: Public Domain, developed and released by Linguistic Society of Hong Kong (LSHK) in 1993. - Ref (Chinese): http://www.lshk.org/cantonese.php * Quick*: directly derived from Cangjie* and put into Public Domain. * scj6: GPL-3, also referenced in debian/copyright - Ref: http://download.scj2000.net/src/COPYING * Stroke5: GPL-2+, also referenced in debian/copyright - Ref: http://code.google.com/p/ibus/wiki/ChineseTableLicenseAuditing * Wu: GPL-2+, also referenced in debian/copyright - Ref: http://input.foruto.com/wu/index.html * Zhengma: CN1043210 (89108851.2), expired in 2009. - Ref (Chinese): http://www.china-e.com.cn/main/zhengma/jj.htm Clean room implementation of common tables: http://qiangheng.openfoundry.org Reference: 1.http://www.angelfire.com/mn/10key/patents.html (BIG-5 encoded Chinese and English text) 2.http://code.google.com/p/ibus/wiki/ChineseTableLicenseAuditing (outdated on expiration info) The binary packages are not arch-all because there is endianness issue with these data files. -- Aron Xu Tue, 04 May 2012 00:39:30 +0800
