?Anchor(Redistribution)

Redistribution

Allow to redistribute the content in various forms (raw, html, pdf, encrypted...) and on various media (packages, cd). This feature is Required.

?Anchor(Allow_Modification)

Allow Modification

Allow modification by others (add and remove). This feature is Required.

?Anchor(Allow_Derivative)

Allow derivative works

Allow Debian derivative distribution to use the document. Allow to reuse content in package Documentation, etc. This feature is Required.

?Anchor(Share_Alike)

?Anchor(Allow_Commercial)

Allow commercial use
Allow commercial Debian derivative to reuse the material.
  • Mix / Merge with other documents (with same or compatible license) : Yes.

  • Attribution : _not_ wanted (Even thought we actually want to attribute the work to their original author, I believe it isn't possible to guarantee that all work attribution will be preserved over time. Furthermore, the actual name of the author isn't always known)

  • Allow commercial uses of your work ??? (probably yes : Debian has commercial derivatives. We don't want to prevent those derivatives from providing a package that contains a copy of the wiki).

  • 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.
