Breaking the default wiki into separate applications

Hi, I've started doing the exercise of breaking up XWiki Enterprise (aka the default wiki) into applications. Here's what I came up with: - Administration Application User and Group management, etc - Blog Application - Calendar Application - Class Wizard Application - Help Application Wiki Syntax Sheet and potentially other pages to help the user with his wiki. - Navigation Application All pages that make it easy to navigate in a Wiki. Includes What's New, Orphaned Pages, All Docs, Space Index, Dashboard, RSS feeds for new pages/modified pages/comments. - Photo Album Application - Presentation Application - Search Application - Tag Application Of course there also some documents in the Enterprise wiki that don't belong to an application as they are specific (for example the Main.WebHome page). I have created these components in JIRA for the http://jira.xwiki.org/ jira/browse/XE project. In the future the idea is to move these applications in SVN (as it's currently done for the Panels and Selenium applications) and to create separate JIRA project for them. Have I missed an application? WDYT? Thanks -Vincent
