Configuration Made Easy: TikiWiki has a lot of features and covers a wide range of use cases. Because of this, it is unlikely to work "out of the box" for anyone. Profiles solve this problem by storing and sharing different configurations, feature sets, permissions schemes and pre-made examples of some of the more complicated features. This will address the The Paradox of Choice.
Managed in wiki pages (collaborative, version history, etc.)
Can be used not only at the initial install, but also on an existing installation.
Install one or many, even if they overlap (the last one installed wins if there are any conflicts)
Profiles can include other profiles (several small profiles making a large one)
Not just for settings, but also for data
Since there is no extra code, can be designed for very specific, long tail uses or Vertical Markets. We can have hundreds of profiles for an out-of-the-box experience, with a single code-base!
Permits power users & admins to share their experience
Each profile is a configuration patch that can be applied on top of any TikiWiki installation. Profiles will allow to change configurations in a TikiWiki installation and create various objects. As of now, the most important object types are available and more will be added as needed.
