The Historical Permission Notice and Disclaimer is an open source license, approved by the Open Source Initiative (OSI). It is unique among the OSI's licenses because of the choices it allows in its construction; it lets the licensor pick anywhere from 0-2 warranty disclaimers, whether they want to prohibit your publicity of the software derivatives (like in the BSD License), and other spelling and grammar options. Besides this, the license can be almost functionally identical to the new 3-clause BSD License (if the option for the no-promotion clause is exercised), or the MIT License (if the option for the no-promotion clause is not exercised).
Variants of this license are in use primarily in older software, including the original BSD kernel, developed by IBM, Intel and others. Today, it is most popular to choose either the new 3-clause BSD License or the MIT License to meet the licensing needs of the developer.
This is the only OSI-certified license (excluding the public domain) that can lack a disclaimer of warranty. The Free Software Foundation has not yet recognized this license as a free software license in the general case, but has done so for certain variations, such as that used for versions of Python before 1.6b.
Famous quotes containing the words historical, permission and/or notice:
“We can imagine a society in which no one could survive as a social being because it does not correspond to biologically determined perceptions and human social needs. For historical reasons, existing societies might have such properties, leading to various forms of pathology.”
—Noam Chomsky (b. 1928)
“Misfortune is never invited. And it comes and sits at the table without permission and it eats, leaving nothing but bones.”
—Jacques Roumain (1907–1945)
“Mildred Pierce: You look down on me because I work for a living, don’t you? You always have. All right, I work. I cook food and sell it and make a profit on it, which, I might point out, you’re not too proud to share with me.
Monte Beragon: Yes, I take money from you, Mildred. But not enough to make me like kitchens or cooks. They smell of grease.
Mildred Pierce: I don’t notice you shrinking away from a fifty- dollar bill because it smells of grease.”
—Ranald MacDougall (1915–1973)
