The Wikimedia Foundation is the supporting organization of Wikipedia and its sister projects. Together with a developer community, it develops MediaWiki and many extensions. From there we adopt a stable and proven technology with high performance.
Hallo Welt! extends the existing functionality and develops many own extensions.
We publish our extensions in the public repositories of the Wikimedia Foundation and thus give our development back to the community. Hallo Welt! is one of the largest contributors and maintainers of extensions. A current statistic can be found here.
The translation of the interface is largely done by the great MediaWiki translation community (project translatewiki).
Employees of Hallo Welt! also actively participate in community conferences and in the MediaWiki Stakeholder user group.
With on premise systems, this is technically possible at any time.
In order to be able to support you optimally and quickly in the event of a malfunction, we agree with our contract customers that any intervention in the source code will only be carried out by Hallo Welt! Excluded from this rule are systems that are managed with a version control system (e.g. git) or all changes within the interfaces released by Hallo Welt! (e.g. CSS adjustments).
Complete independence from a vendor can never be achieved. But if you should stop working with us, you have the option
continue to use the wiki without updates and upgrades after the end of the contract period,
revert BlueSpice pro or farm to the free version in order to continue working – but with the reduced scope of the free version,
revert the wiki to a MediaWiki or
migrate your data to other solutions or to another MediaWiki service provider.
The most important fallback solution remains MediaWiki. This opens up long-term perspectives for you, since Wikipedia’s software is being developed for the long term and, as far as we can estimate today, will always be available as open source software.
