Definition fluide extensions
From MediaWiki extension testing
Fuide extension are extension who can be generated on the fly by Wikiation installer. This is very flexible. You can fine tune as much as you like.
But it take a bit more preparation.
When often installing and de-installing extensions these extension are called fluid. They are not allways available when needed. When you need extension which are allways available choose persistent extensions.
Conclusion
A persistent extension is just a normal MediaWiki extension. It just indicate how it is used in the extension testing enviroment. A fluide extension must be installed by you before you can use it. Its a bit more work, but the choise you have is much larger then with persistent extensions.
