3 += A bit of history =
4 +
5 +Before the introduction of the Nested Pages concept (in 7.2), the content in a wiki was organized like this:
6 +* we had some **Spaces**, that you can see as "folder"
7 +* inside these spaces, we had **Pages**, where you were able to write some texts or store applications entries.
8 +
9 +In that time, we cannot have spaces inside spaces, so all pages were placed inside a one-level space. The pages were identified like this: ##NameOfTheSpace.NameOfThePage##.
10 +
11 +Some pages were a bit special. They were the "home" page of a space. Every time a user wanted to reach a space without specifying a precise page name, she was redirected to that space home page. These pages were called "WebHome" (because at the very beginning of XWiki, "spaces" were called "web").
12 +
13 +== Parent/Child relationship ==
14 +
15 +The user was able to specify a **parent** page for each page she had created. This parent could have been any page, for example the page ##Movies.ItsAWonderfulLife## could have ##Directors.FrankCapra##. Then ##ItsAWonderfulLife## was listed as ##Child## of ##FrankCapra##.
