This might take the form of a Horde-wide (per-user of course) "trash folder", or some other form of undeletion or revision history. One suggested approach is to embed this into a larger task to implement journaling in Horde. This would look include these tasks: * Horde_Journal library with SQL and potentially MongoDB backends (5 hours) * Journaling for apps (10 hours): Use Horde_Journaling in Kronolith, Nag, Turba, Mnemo to track additions, changes, deletions. * Collection (calendars, address books, etc) history (10 hours): Application support (backend and UI) to retrieve and display journal summaries for a groupware collection. Maybe on-demand for dynamic frontends? * Object history (10 hours): Application support (backend and UI) to retrieve and display complete journal for a groupware object. Maybe on-demand for dynamic frontends? * Undo (25 hours): Implement undo functionality based on the journaling features for end users. Time estimations are probably too optimistic, especially for the base journaling functionality. ----------- Resources ----------- http://www.alistapart.com/articles/neveruseawarning http://bergie.iki.fi/blog/undeletion_in_midgard.html http://paulbuchheit.blogspot.com/2007/06/quick-all-actions-should-have-undo.html http://humanized.com/weblog/2007/09/14/undo-made-easy-with-ajax-part-1/ http://azarask.in/blog/post/undo_with_ajax_2/ http://ajaxian.com/archives/addressbook-an-example-of-the-form-history-pattern ---- Back to the `Project List`_ .. _`Project List`: https://wiki.horde.org/Project?referrer=Project%2FUndo
