===Debian Free Software Guidelines===
The '''Debian Free Software Guidelines''' ('''DFSG''') was first published together with the first version of the [[Debian Social Contract]] in July 1997.<ref name="1997-msg00017">{{cite web|author=Bruce Perens|url=http://lists.debian.org/debian-announce/debian-announce-1997/msg00017.html|title=Debian's "Social Contract" with the Free Software Community|work=debian-announce mailing list|date=1997-07-04}}</ref> The primary author was [[Bruce Perens]], with input from the Debian developers during a month-long discussion on a private mailing list, as part of the larger Debian Social Contract. Perens was copied to an email discussion between Ean Schuessler (then of Debian) and Donnie Barnes of Red Hat, in which Schuessler accused Red Hat of never elucidating its social contract with the Linux community. Perens realized that Debian did not have any formal social contract either, and immediately started creating one. The (then) Three Freedoms, which preceded the drafting and promulgation of the DFSG, were unknown to its authors.<ref>Bruce Perens: "[http://news.slashdot.org/comments.pl?sid=1129863&cid=26875815 when I had to write license guidelines for Debian, the Four Freedoms document was unknown.]"</ref>

The guidelines were:
# Free redistribution.
# Inclusion of source code.
# Allowing for modifications and derived works.
# Integrity of the author's source code (as a compromise).
# No discrimination against persons or groups.
# No discrimination against fields of endeavor, like commercial use.
# The license needs to apply to all to whom the program is redistributed.
# License must not be specific to a product.
# License must not restrict other software.
# Example licenses: The [[GNU General Public License|GNU GPL]], [[BSD license|BSD]], and [[Artistic License|Artistic]] licenses are examples of licenses considered free.<ref name="1997-msg00017" /><ref>{{cite web
