Proposed licenses

Here are some proposed licenses for the wiki.

?Anchor(GFDL)

GFDL 1.2

[http://www.fsf.org/licensing/licenses/fdl.html GFDL] 1.2 License ([wiki:DFSGLicenses Debian DFSG], [wiki:GNU_Free_Documentation_License Wikipedia])

Attribution :
The GFDL really focus on attribution, which is a feature we don't want that much.

?Anchor(MIT)

MIT

[http://www.opensource.org/licenses/mit-license.php MIT] License ([wiki:DFSGLicenses Debian DFSG], [wiki:MIT_License Wikipedia])

Attribution enforced :

Copyright (c) <year> <copyright holders> [..] The above copyright notice and this permission notice shall be included in all copies However it also says or substantial portions of the Software.

?Anchor(BSD)

BSD

[http://www.opensource.org/licenses/bsd-license.php BSD] License ([http://www.freebsd.org/copyright/freebsd-doc-license.html FreeBSD] copy, [wiki:?DFSGLicenses# Debian DFSG], [wiki:BSD_licenses Wikipedia]).

Attribution enforced :

Copyright (c) <YEAR>, <OWNER> ; All rights reserved. [..] Redistributions of source code must retain the above copyright notice, this list of conditions and the following disclaimer.

?Anchor(public-domain)

Public Domain

Public domain interpretation : [http://creativecommons.org/licenses/publicdomain/ Creative Commons], [wiki:Public_domain Wikipedia].

Implicit public domain don't allow duplication :

[..] The distribution of many types of Internet postings (particularly Usenet articles and messages sent to electronic mailing lists) inherently involves duplication. The act of posting such a work can therefore be taken to imply consent to a certain amount of copying, as dictated by the technical details of the manner of distribution. However, it does not imply total waiver of copyright.([http://en.wikipedia.org/wiki/Public_domain#.28Almost.29_everything_written_down_is_copyrighted wikipedia]).

Implementation ideas

  • The front page should state the default license.
  • On change-commit, the license should be displayed.
  • The [:DebianWiki/EditorGuide:?EditorGuide] :

    • Should link to "default license page".
    • Should state that specific license are only accepted in specific, exceptional and justified cases. Otherwise, the content will removed from the wiki.
