DocBookWiki can display and edit DocBook documents online. It can display several documents at once (a list of books), and each of them can be in several languages. Editing can be done in several modes (like text/wiki, HTML, XML, etc.), but the basic format is always XML/DocBook. Each document can be automatically converted into other formats for downloading. The history of modifications is kept in SVN, and any previous versions of a document can be recovered.
