Leading Gephi development
The Gephi Consortium is a not-for-profit corporation created to join the efforts of industrials, laboratories and civil society in building Gephi, an open source software for network visualization and analysis.
Since 2008 the Gephi Team progressively opened the project. Choosing a Free Software license - GNU GPLv3 - was the first step, quickly followed by a website and the use of the Launchpad platform. Then one year passed to reach the capability to open the contributions with a new framework, in 2009. Today the software is world famous thanks to our community, and the code base is mature enough to start an international expansion. The Gephi Consortium is our solution to foster the evolution and exploitation of the Gephi Open Source projects in a sustainable way.
The Consortium makes an R&D effort to build generic and reusable parts of Gephi, improve a competitive technology at low cost, and create standards to ensure interoperability. Our mission is to provide core services to the Gephi community, support the development of the Gephi Open Source framework, and help other projects around it like the GEXF universe (format specifications, libraries and Flex applications). We act as a central point to coordinate the worldwide distributed development, promote it and legally protect it.
These goals are only reachable with the financial and in-kind support of the community. Linkfluence SAS, INST-CNRS and WebAtlas NGO have joined us as founding members. They have been selected to their past investments to support Gephi at the early stages.
The ecosystem we set up is made for the benefit of the whole community. The governance is held by a Board of Directors electing the Management Office every three years. The consortium has the right to only receive funding from grants, donations and membership fees to ensure the respect of antitrust laws. Contracts are then held by members on their sole commitment, out of the consortium's responsibility scope.
We expect this way to generate opportunities for companies to build by-products and services, Gephi developers to get hired for their recognized skills, analysts to improve their insights as long as our technology evolves, and academics to use a robust infrastructure for visualization and network science research for free.
The Gephi Consortium has officially started on October 1st, 2010.
The Gephi Consortium is a non-profit organization governed by the French law of July 1st, 1901, equivalent of the United States 501(c)(3) organization. The Consortium consists of individual members, corporate members, a Management Office and a Board of Directors.
The Management Office shall establish three Councils in order to assist the Board of Directors and provide guidance to the Management Office: an Operations Council, a Technology Council and an Ecosystem Council:
In addition to the officers of the corporation, the Board of Directors may establish one or more Project Management Committees, responsible for the active management of one or more projects.
Members of the Board of Directors are elected in the following manner:
The current list of the Gephi Consortium members may be found at this page.
Gephi is an open source software for network visualization and analysis. Like Photoshop™ but for data, Gephi helps data analysts to intuitively reveal patterns and trends, highlight outliers and tells stories with their data.
All software developed within the Consortium belongs to the Gephi Consortium, and therefore the committers. The CLA, signed by every contributor, is a license agreement only; it does not transfer copyright ownership and does not change the committers' rights to use their own contributions for any other purpose.
Sure. Our products are Free software, both as in speech and as in beer, and there are no fees or notification requirements. If you plan to reconfigure it and then sell the machines, please contact us.
The Gephi Consortium is still in the making. Currently we need help essentially to:
Please contact Sebastien Heymann:
Yes. In summary, the Contributor License Agreements asserts that when you donate fixes or documentation, you are the owner of your work and allows the Gephi Consortium to use it in every ways possible.
Membership is open to all types of organizations including commercial, educational and governmental organizations, as well as individuals. Any entity which can sign the Membership Agreement can become a Member.
There has three main categories of membership: Strategic Members, Corporate Members and Individual Members. The dues, rights and duties of all categories are defined in the Membership Agreement [pdf] and are subject to evolve.
Strategic Members are legal entities who stand out to provide significant resources to support the Association’s objectives and wish to play an active role both in setting the direction of the Association’s code development activities and facilitating the use and acceptance of the Association’s technology. Strategic Members commit to remain members for a minimum of three (3) consecutive years.
Corporate Members are legal entities that wish to contribute to the code development activities of the Association, to participate in the planning and management of the Association’s technology development process and to facilitate the use and acceptance of the Association’s technology.
Individual Members are individuals such as free-lancers, students and technology enthusiasts who meet the requirements of an Individual Member as set forth in the then current Association Membership Agreement, under the heading “Individual Members”. No paid employee or contractor of a Strategic Member or a Corporate Member shall be considered an Individual Member unless having joined in person as an Individual Member. Likewise no organization shall be considered a Member (either a Strategic Member or a Corporate Member) by the sole virtue of a paid employee or a contractor having joined the Association as an Individual Member.
No. Annual fees are:
Organizations not able to join the Gephi Consortium for any reason but willing to participate in a Development Program are registered as Associate Organization for free. However it does not confer any Membership right in the Gephi Consortium.
Strategic Members are organizations which commit their dues for three years as well as in-kind contribution such as full time staff to help run the organization.
We focus on the specifications and development of the Gephi Open Source core. This R&D effort for building generic and reusable parts is only made possible by the collaboration of multiple companies, research laboratories and organizations.
While all of the administrative effort is currently through unpaid volunteers, we also need financial assistance to keep our work running. Expenses include:
The Consortium’s activities for software development are organized into Projects. A Project regroups development actions corresponding to one or more technical software components, or the integration of different technical components in order to build a platform.
Members participation to the source code are undertaken during Development Programs. A Development Program is a close technological cooperation between the Association and the Member to improve some parts of the technical ecosystem. Multiple Members can join the same Development Program to lower costs.
In this answer, a "license" means a given version of a given license.
1) License choice
Any OSS license may be accepted, as defined by our Intellectual Property Rights Policy (paragraph 1.7) [pdf]. The Board makes the final decision. When accepted, the license should be immediately published on the project's web pages.
2) License change
Any license change requires a Board decision. When accepted, the license change should be immediately published on the project's web pages.
3) Board decision guidelines
Yes, unless you modify the source code of the Gephi Toolkit.
The Gephi Toolkit is designed to be used as a library, so you are free to choose the license of your application.
Yes, you have to publish the modified source code of the Gephi Toolkit if you distribute it. However you do not have to do so with the whole application.
Yes, but only the modified source code of the Gephi Toolkit.
Yes. The Gephi Consortium recognizes that its members may choose to engage in dual licensing business practices. Each Member remains free to license outside of the Project hosted by the Consortium its own software contribution under any other license. The rule is that commercial companies engaged in dual licensing business model must allow third-party committers on the code.
Gephi software is itself distributed in dual license (CDDL and GNU GPLv3) by the Gephi Consortium. Contact us to learn more.
The appropriate trademark symbol (TM or similar) should appear with at least the first use of any Gephi Consortium trademarks within a document or graphic, and with all occurences of the Gephi Consortium logos.
When you use a Gephi trademark or logo, you should include a statement attributing the trademark to The Gephi Consortium. For example, "Gephi Desktop and Gephi Toolkit are trademarks of The Gephi Consortium."
See our Visual Identity guidelines.
Please don't. The logos are trademarked, and so if the result is confusingly similar to the original, or used in a confusing manner, it's a violation of trademark law.
Approval is not required for the following fair uses of the Gephi Consortium marks:
You may also use screenshots of the Gephi Consortium products in commercial books and publications, both where the products are the focus and where they are not (e.g. screenshots of web pages or emails).
No. Many free software licenses explicitly exclude rights to trademarks, and so trademark restrictions on otherwise free software is accepted by the community. We are using our trademarks as a mark of quality to protect consumers - we think this is very much within the principles of free software.
If your question isn't covered here, time to move on to the Trademark Policy document (download ).
