Indeed, right now, the best practice is a top level space named after the app (https://dev.xwiki.org/xwiki/bin/view/Community/ApplicationDevelopmentBestPractices). I guess the reason we didn’t do anything else is because we lacked an agreed proposal simply. > Comparing with how other platforms do is inspirational (Microsoft Windows > "Program Files" was mentioned in the thread).

I feel it would be better to have an “Applications” subspace as in: XWiki |_ Applications |_ MyApp |_ … |_ Users |_ … This allows to put other things in the XWiki space, such as users for example. Note that for me the main reason to avoid putting spaces at the root is to avoid using up namespaces that can then no longer be used by users. In this spirit the minimum we could do is reserve only the “XWiki” space. > 2) Data: the pages created by MyApp could then typically be located by > default in a MyApp space at the root of the wiki, the user could however > choose which default space to use, or leave it empty (then the space from > where the user fires the create action could be used, for instance, or any > scriptable rule). Why not. I’m just not sure I would mix app data pages with pure content pages and use up namespaces at the root (you end up with the same issue as I mentioned above and you below). I agree that data pages shouldn’t go in the /XWiki/Applications space though which should be readonly. So there are some other options: * In /XWiki/Data/MyApp * Reserve another namespace entry at the root (“Data”): /Data/MyApp You said " the user could however choose which default space to use”. How would you plan to implement this? Right now, this would work only if the app provides a template and the user uses this template to create a new page. For example the FAQ app doesn’t do that and it provides a UI to create a new FAQ entry and this goes in /FAQ/ directly. > > Another issue I see with the current practice (raised by Clément A. orally) > is that some application names may conflict with names the user would like to > use for content that is not strictly related to the app. Not necessarily a > big deal with one thousand of applications, but might become one with more, > wouldn't it? Sure and you get the same issue with your proposal of putting app data at the root under /MyApp, no? > I understand that the layout proposed above would raise technical issues > (XWiki space permissions for instance, mentionned in the 2015 thread, and > others), however what's your view on it from a design perspective? (sorry if > I overlooked strong arguments already expressed against it) Thanks for starting this thread again. One other point missing in this discussion is the migration from the current status to any target. How would we achieve it? How do we migrate an app to follow any new best practice without breaking users? (Idea: https://design.xwiki.org/xwiki/bin/view/Proposal/DocumentAliases). Let’s start the discussion ;) Thanks -Vincent > > Cheers > > Stéphane >
