procedureThe 'Dissident test,' used by the debian-legal mailing list to check for Debian Free Software Guidelines (DFSG) compliance, considers whether a dissident in a totalitarian state can share modified software with other dissidents without being forced to reveal their identity, the modifications, or their possession of the program to the government.
accountRichard Stallman promoted the Free Software Definition to differentiate free software from open source after the Debian Free Software Guidelines (DFSG) became the Open Source Definition.
claimDocumentation licensed under the GNU Free Documentation License (GFDL) by the GNU Project, the Linux Documentation Project, and others often contains invariant sections that do not comply with the Debian Free Software Guidelines (DFSG), as established by the Debian General Resolution 2006-001.
claimThe Debian project publishes the 'Debian Social Contract and Free Software Guidelines' to define the criteria for free software within the Debian operating system.
referenceThe Debian Free Software Guidelines consist of the following criteria: free redistribution, inclusion of source code, allowing for modifications and derived works, integrity of the author's source code, no discrimination against persons or groups, no discrimination against fields of endeavor, the license must apply to all to whom the program is redistributed, the license must not be specific to a product, and the license must not restrict other software.
accountThe creation of the Debian Social Contract and the Debian Free Software Guidelines was prompted by an email discussion between Ean Schuessler of Debian and Donnie Barnes of Red Hat, in which Schuessler accused Red Hat of failing to elucidate its social contract with the Linux community, leading Bruce Perens to realize that Debian also lacked a formal social contract.
claimThe Debian Free Software Guidelines were first published in July 1997 as part of the first version of the Debian Social Contract.
procedureThe 'Desert Island test,' used by the debian-legal mailing list to check for Debian Free Software Guidelines (DFSG) compliance, posits that software must be modifiable and shareable by a castaway on a desert island with a solar-powered computer, even if that person cannot send patches or make changes publicly available.
accountIn November 1998, Ian Jackson and others proposed changes to a draft version 1.4 of the Debian Free Software Guidelines, citing "loose wording" and the patch clause as issues, though these changes were never made official.
claimNon-program content in the Debian operating system began to comply with the Debian Free Software Guidelines (DFSG) more strictly starting with the release of Debian 4.0 in April 2007.
claimBecause the GNU Free Documentation License (GFDL) allows for invariant sections that violate the Debian Free Software Guidelines (DFSG), content licensed under the GFDL must be stored in a separate 'non-free' repository that is not officially considered part of Debian.
claimThe Debian Free Software Guidelines (DFSG) were originally focused on software, but the definition of 'software' was ambiguous, leading the Debian project to explicitly apply the same principles to software documentation, multimedia data, and other content in June 2004.
