Concept
Artistic License
Résumé
The Artistic License is an open-source license used for certain free and open-source software packages, most notably the standard implementation of the Perl programming language and most CPAN modules, which are dual-licensed under the Artistic License and the GNU General Public License (GPL).
The original Artistic License was written by Larry Wall. The name of the license is a reference to the concept of artistic license.
Whether or not the original Artistic License is a free software license is largely unsettled. The Free Software Foundation explicitly called the original Artistic License a non-free license, criticizing it as being "too vague; some passages are too clever for their own good, and their meaning is not clear". The FSF recommended that the license not be used on its own, but approved the common AL/GPL dual-licensing approach for Perl projects.
In response to this, Bradley Kuhn, who later worked for the Free Software Foundation, made a minimal redraft to clarify the ambiguous passages. This was released as the Clarified Artistic License and was approved by the FSF. It is used by the Paros Proxy, the JavaFBP toolkit and NcFTP.
The terms of the Artistic License 1.0 were at issue in Jacobsen v. Katzer in the initial 2009 ruling by the United States District Court for the Northern District of California declared that FOSS-like licenses could only be enforced through contract law rather than through copyright law, in contexts where contract damages would be difficult to establish. On appeal, a federal appellate court "determined that the terms of the Artistic License are enforceable copyright conditions". The case was remanded to the District Court, which did not apply the superior court's criteria on the grounds that, in the interim, the governing Supreme Court precedent applicable to the case had changed. However, this left undisturbed the finding that a free and open-source license nonetheless has economic value. Jacobsen ultimately prevailed in 2010, and the Case established a new standard making terms and conditions under Artistic License 1.
