Hi Devs, Appart from the “conventional” application that manage their own data subset, there is more general application, that are either providing wiki-wide feature without data, or that are managing data in the whole wiki, providing additional features. For example, the Administration application, the CKEditor, … and other application actually mixed in the XWiki space.
For those applications, the code/data space separation has no real meaning, but I think it would also be nice to have the code of those applications under a common root, in place of having all of them creating a space at the root of the wiki. For example, currently the UI of the CKEditor is in a CKEditor space at the root, and I have no easy way to distinguish it from a normal space (except that it is invisible), and it is also holding a space name. I agree, there is little chance that a user wants to create an editorial space by the name, but it could happen, and depends on the application space name, there could be more common cases. My proposal is to put such application inside a common space. There is several options for the name of that space: A) Reuse the existing “XWiki” space Pros: - not holding a new name at root - always available - nice place to move application already mixup in that space to their own space Cons: - it is currently a mess - it holds users (but shouldn’t we move them to Users space ? I know it is not easy) B) Create a new space for this purpose B1) XWikiApplications B2) XWikiExtensions B3) WikiApplications B4) WikiExtensions B5) Wiki B6) … ? wdyt ?
