== GPL Licentie ==GPL staat voor General Public License. De meest gebruikte licentie is de GNU General Public License[1], of afgekort GNU GPL . Dit kan verder afgekort worden tot "GPL", wanneer het duidelijk is dat de GNU GPL wordt bedoeld. [2]

Over Joomla! en GLP

Het Joomla! project is een GPL community, wat niet alleen betekent dat een specifieke Gratis en Open Source licentie wordt gebruikt voor Joomla!, maar ook dat we geloven in de missie en waarden achter deze licentie. Dit bevat ook samenwerken, community en vrijheid. De GPL licentie belichaamt deze waarden.

  • Welke GPL versie gebruikt Joomla! ? Joomla! os gelicenseerd onder de GPL versie 2 of nieuwer.

De Joomla! Extensions Directory en GPL

The Joomla! Extensions Directory (JED) is important for many reasons: it makes it easier for users to find extensions, and it helps support the development of a vibrant and healthy commercial and non-commercial development community around Joomla. However, it may also be unintentionally undermining our support of the GPL by including extensions and other applications that run counter to it. The Joomla! Project has determined that the Joomla! Extensions Directory (JED) should be a community resource that fully embodies the project's values, especially freedom as embodied by the GPL license.

  • Since March 31 2009 the Joomla! Extensions Directory (JED) no longer accept non GPL and since July 1 2009 only GPL extensions are allowed to be listed here [3].
  • These changes were designed to strengthen the project's commitment to its core mission, vision and values as articulated in September 2008[4].

GPL Licentie vereist

Extensions must be licensed as GPL in order to be listed Additional restrictions may not be placed on top of the GPL.

Extensie pakketten - algemene eisen

JED needs to be able to monitor files and make it easier for users to understand the terms under which they purchase/download extensions. This is why, to be listed at JED, you need to comply with additional terms that will improve directory maintenance and trust from directory users.

  1. Publish under a GPL license - See: Versions of the license
  2. Include GPL notices on XML and PHP files - See: Examples and how-to.
  3. Verzorg een kopie van de GPL-licentie in uw pakket:
    1. dit bestand hoeft niet te worden geïnstalleerd, alleen maar meegeleverd in het pakket als tekstbestand
    2. Er is een tekst beschikbaar om te kopiëren en als bestand op te slaan: [5]
  4. Copyright notice in all files as required by GPL license[6].
  5. Encrypted or encoded extensions, whether or not they are GPL licensed, will also be excluded.

Forked extensions

We support the original project developer whenever possible to maintain the integrity of the listings and also support developers who are building and innovating on the Joomla! platform.

Forked project must represent a significant code improvement, either in features or security and structure.

Snelle Vraag en Antwoord

  1. Who will you intend to support developers? The Joomla! team is strongly committed to supporting both commercial and non-commercial Joomla! developers. We have implemented some policy changes to enhance our support for developers. Therefore we will not link to collections of GPL extensions that are not submitted by the original developer.
  2. Betekent dit dat er geen commerciële extensies in de JED komen?

Nee! Commerciële extensies met de GNU GPL licentie en die niet gecodeerd zijn zijn welkom en worden aangemoedigd om in de JED te komem.

  1. Who will be able to submit extensions? Only the original developer! We think that the best place to get an extension is from the original developer of that extension.
  2. What if I think my extension doesn't violate the Joomla! license? This is a policy in favor of software freedom and the mission, vision and values of the Joomla! Project, not one about technical issues in licensing.
  3. Kan ik gebruik maken van een GPL-compatible licentie? Nee! De JED zal alleen extensies opnemen die onder de GNU GPL licentie vallen. De enige licentie die echt de ware belichaming van GPL is, is de GPL.
  4. Kan ik in mijn GPL extensie de bibliotheken gebruiken die GPL compatibel zijn? Ja!
