Thunder is a Drupal 8 distribution for professional publishers. It consists of the current Drupal 8 functionality, lots of useful modules from publishers and industry partners, and an environment which makes it easy to install, deploy and add new functionality.

The distribution is maintained by the Thunder Core Team ([email protected]). The Core Team decides which modules are added to or removed from the distribution. The Core Team also ensures that all basic functionality is available free of charge.

No. Just download and go ahead. If you would like to receive news about thunder, sign up to our newsletter by sending ‚Subscribe‘ to [email protected]. If you want to contribute or collaborate or influence the development: join the Thunder Coalition by requesting the member form at [email protected].

Publishers using Thunder are encouraged (but not obliged) to join the Thunder Coalition (member request form) and add new functionality to the distribution. But this is completely up to you or your company’s regulations.

Industry partners may add functionality to Thunder, provided that this functionality is useful for publishers, free of charge for unlimited time and that the industry partner is invited and/or accepted by the Core Team. Please inquire using the member form.

The Thunder Coalition offers industry partners to have their software or services used by many publishers. The industry partners may also offer additional premium functionality, which publishers might want to use and also pay for.

No. If a publisher wants to procure premium functionality from any industry partner, the Thunder Coalition is not involved. Any contract is established directly between the respective industry partner and the publisher.

In general, neither Hubert Burda Media, nor the Thunder Core Team, nor any other individual or organisation who contributes to the functionality included in the Thunder distribution under the GNU General Public License (i.e. for free) can be held liable for any bugs, crashes or any other actual or perceived misperformance of the software or the system. However, individual service level agreements may be negotiated for premium services provided on top of the Thunder functionality by industry partners to specific clients.

Thunder offers small companies and individuals to become certified Thunder specialists.

Specialists are also Coalition Members. Please request the member form from [email protected] and fill in the specialist part.

Industry partners, publishers, individuals, implementation partners and the core team form the Thunder Coalition. The goals of the coalition are

• to enable publishers to deploy rich functionality for their products very quickly and at reasonable cost,
• to share functionality among publishers, fuelling the industry and providing excellent user experience with the individual content,
• to enable industry partners to spread their outstanding services amongst publishers and to charge for premium services as the publishers grow,
• to enable implementation partners to gain knowledge about Thunder programming and implementation in order to provide services to publishers and industry partners.

The Coalition discusses feature requests and offers, celebrates new launches, and is a platform for programmers and executives in the publishing industry. There is mailing list, a forum and the Coalition will meet face to face annually starting in June 2016.

The Thunder Core Team are a small number of publishing experts and computer scientists led by Ingo Rübe. They maintain the distribution, handle industry relations, publishers’ requests and offers as well as specialists training. They also run the Coalition’s infrastructure (like thunder.org) and organise events like the annual meeting.

The Core Team’s expenses are paid by Hubert Burda Media. There is no plan to earn money. Hubert Burda Media believes that the Thunder Coalition will speed up their own development so much, that the investment in the core team will pay back easily in the form of improved functionality and the sharing of knowledge and ideas.

Forever? probably not alone. However, Hubert Burda Media will fund the initiative for a significant period that is long enough to establish Thunder in the market. If Thunder is successful, we might change the funding to a foundation model like Apache.org in a couple of years.

Please report to [email protected] describing the module and the effect. If you can fix the bug yourself, please go ahead and either inform [email protected] or use the mechanisms on drupal.org.
