The Apple Public Source License is the open source and free software license under which Apple's Darwin operating system was released. A free software and open source license was voluntarily adopted to further involve the community from which much of Darwin originated.
The first version of the Apple Public Source License was approved by the Open Source Initiative (OSI). Version 2.0, released July 29, 2003 conforms to the Free Software Foundation guidelines, and is also approved by the OSI. The Free Software Foundation approved the Apple Public Source License 2.0 as a free software license and say it is acceptable for developers to work on projects that are already covered by this license. They recommend, however, that developers do not release new projects under this license, because the partial copyleft is not compatible with the GNU General Public License and allows linking with files released entirely as proprietary software. The license does, however, require that if any derivatives from the original source are released externally, that the source be made available.
Many software releases from Apple have now been relicensed under the more liberal Apache License, such as the Bonjour Zeroconf stack.
Famous quotes containing the words apple, public, source and/or license:
“The apple doesn’t fall far from the tree.”
—Swedish proverb, trans. by Verne Moberg.
“It is because the public are a mass—inert, obtuse, and passive—that they need to be shaken up from time to time so that we can tell from their bear-like grunts where they are—and also where they stand. They are pretty harmless, in spite of their numbers, because they are fighting against intelligence.”
—Alfred Jarry (1873–1907)
“Nothing could be more inappropriate to American literature than its English source since the Americans are not British in sensibility.”
—Wallace Stevens (1879–1955)
“I go out of my way, but rather by license than carelessness.... It is the inattentive reader
who loses my subject, not I. Some word about it will always be found off in a corner, which will not fail to be sufficient, though it takes little room.”
—Michel de Montaigne (1533–1592)
