6.2. Licensing and Copyright

In order for a document to be accepted by the LDP, it must be licensed and conform to the "LICENSE REQUIREMENTS" section of the LDP Manifesto located at http://www.tldp.org/manifesto.html.

We recommend using the GNU Free Documentation License (GFDL), one of the Creative Commons Licenses (Share-Alike, or Attribution-Share-Alike), or the LDP license (currently under review). The full text of the license must be included in your document, including the title and version of the license you are using. The LDP will not accept new documents that do not meet licensing requirements.

WarningDebian-compatible licenses

The Debian package maintainer for LDP documents has divided the LDP documents into those with a "free" license and those with a "non-free" license. For a summary of this list, please read Debian License Summaries. Currently the Artistic License, BSD License and the GNU General Public License are listed as "free". These licenses will also be accepted by the LDP. The definition of "non-free" has not been made transparent. By choosing another license that has any kind of restriction on redistribution or whether or not the document may be modified, your document may be put into the "non-free" package instead of the "free" package. We are working with Debian to clarify how these decisions are made.

You can get DocBook markups of both the GNU GPL and the GNU FDL from the GNOME Documentation Project. You can then merely include the license in its entirety in your document. A DocBook-formatted copy of the license is available in Appendix A.
