The Netscape Public License (NPL) is a free software license, the license under which Netscape Communications Corporation originally released Mozilla. Its most notable feature is that it gives the original developer of Mozilla (Netscape, now a subsidiary of AOL), the right to distribute modifications made by other contributors under whatever terms it desires, including proprietary terms, without granting similar rights to these other contributors in respect to contributions made by the original developer. This allowed the release of the Netscape 6 and later versions as proprietary software.

  • The Netscape Public License (NPL) is a free software license, the license under which Netscape Communications Corporation originally released Mozilla. Its most notable feature is that it gives the original developer of Mozilla (Netscape, now a subsidiary of AOL), the right to distribute modifications made by other contributors under whatever terms it desires, including proprietary terms, without granting similar rights to these other contributors in respect to contributions made by the original developer. This allowed the release of the Netscape 6 and later versions as proprietary software. This asymmetry with respect to rights has led to criticism of the license by many members of the open source and free software movements: the Free Software Foundation acknowledged it as a free-software license but one to be avoided, and the Open Source Initiative either rejected it entirely or was not asked to review it. The FSF adds that it's not possible to combine software obtained under the license with software obtained under the GPL. The Mozilla Public License version 1.1 is similar (and has limited "file-level copyleft"), but lacks the asymmetry in rights. Time Warner, exercising its rights under the Netscape Public License, and at the request of the Mozilla Foundation, relicensed all code in Mozilla that was under the Netscape Public License (including code by other contributors) to an MPL 1.1/GPL 2.0/LGPL 2.1 tri-license, thus removing the GPL-incompatibility.

  • La Netscape Public License (NPL) è una licenza free software, la licenza sotto la quale la Netscape Communications Corporation ha originariamente distribuito Mozilla. La sua caratteristica più importante è che da all'originario sviluppatore di Mozilla (Netscape, ora consociato a Time Warner), il diritto di distribuire le modifiche fatte da altri contributori sotto qualsiasi condizione desideri, anche sotto licenze proprietarie, senza garantire diritti simili a questi altri contributori rispetto ai contributi fatti dallo sviluppatore. Questo permise di rilasciare Netscape 6 e le versioni successive come software proprietario. Questa asimmetria rispetto ai diritti dello sviluppatore originario e gli altri contributori ha portato a forti critiche da molti membri dell'open source e del movimento per il free software: la Free Software Foundation riconobbe questa come una licenza software libera ma da essere evitata, e l'Open Source Initiative rifiutata del tutto. La FSF aggiunge che non è possibile mescolare software ottenuto sotto questa licenza con software ottenuto sotto la GPL. La Mozilla Public License è simile, ma non presenta questi diritti asimmetrici. Time Warner, esercitando i suoi diritti sotto la Netscape Public License e sotto richiesta della Mozilla Foundation, ha ri-licenziato tutto il codice su Mozilla che era sotto la Netscape Public License (incluso il codice di altri contributori) in una tripla licenza MPL/GPL/LGPL, in modo da rimuovere l'incompatibilità con la GPL.

  • Netscape Public License (NPL) は、ネットスケープコミュニケーションズが公開していたMozillaのためのライセンスである。 NPLの大きな特徴は、Mozillaのオリジナルの開発者であるNetscape(後にAOL傘下となる)に対し、他の貢献者による修正をプロプライエタリに変更することも含めて好きなように扱う権利を認める一方で、他の貢献者には同様の権利を認めないことにある。これは、Netscapeシリーズ 6以降をプロプライエタリとしてリリースするためのものであった。 この非対称性は、オープンソースおよびフリーソフトウェアのコミュニティから批判を浴びる原因となった。フリーソフトウェア財団 (FSF) ではNPLを「フリーソフトウェアライセンスではあるが利用を避けるべきもの」とし、GNU General Public License (GPL) と互換性のないライセンスとした。Open Source Initiative (OSI) ではNPLをオープンソースライセンスとして承認していない。 Mozilla Public License 1.1は、NPLと類似しているが前述の非対称性を持たないライセンスである。NPLに基づく権利を有していたTime Warnerは、NPLでライセンスされていたMozillaのコードすべてをMozilla Foundationの求めに応じてMPL 1.1/GPL 2.0/LGPL 2.1のトリプルライセンスで再ライセンスした。 (ja)
