KDE Free Qt Foundation
The KDE Free Qt Foundation is an organization with the purpose of securing the availability of the Qt toolkit
- for the development of Free Software and
- in particular for the development of KDE software.
The Foundation has a license agreement with Digia and Nokia. This agreement ensures that the Qt will continue to be available under both the LGPL 2.1 and the GPL 3. Should Digia discontinue the development of the Qt Free Edition under these licenses, then the Foundation has the right to release Qt under a BSD-style license or under other open source licenses. The agreement stays valid in case of a buy-out, a merger or bankruptcy.
The board of the Foundation consists of two members from Digia and two members from KDE e.V. Decisions of the Foundation are taken by vote of the board members. In case of a tie the votes of the KDE representatives decide.
The Foundation was originally founded by Trolltech and the KDE e.V. in 1998. After Nokia bought Trolltech, the statutes were updated accordingly. In May 2004, a first update to the agreement was made. This agreement addressed the purpose in a more precise and complete way. The intention and basic content however, were not changed. In July 2009, the agreement was again updated to respond both to the relicensing of Qt to the LGPL license and to the merger of Trolltech into Nokia. In November 2009, the statutes of the Foundation where also updated to better fit the new situation.
In October 2011, Nokia launched the Qt Project, allowing both companies and individuals to contribute to the development of Qt under open governance terms. To ensure the fairness of the contribution terms to individual developers, two lawyers were contracted by the KDE Free Qt Foundation. Nokia took their feedback into account and made is thus possible for the KDE Free Qt Foundation to support both the launch of the Qt Project and the wording improvements in the Qt Contribution License Agreement 1.1: “We fully support the work being done with the Qt Project. An openly governed Qt is in the best interests of all Qt developers. The Open Governance structure of the Qt Project empowers developers to influence the direction and the pace of Qt development. Stakeholders in the future of Qt, such as KDE, can now contribute according to their own priorities and take ownership over areas of Qt that are of particular importance to them.” (Olaf Schmidt-Wischhöfer and Martin Konold, the two board members from KDE)
