           Summary: needs a database archive/backup/restore facility
           Product: digikam
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: jjm at keelhaul.me.uk


Version:            (using Devel)
OS:                Linux
Installed from:    Compiled sources

The information in the digikam database may represent a lot of hard work -
tagging, commenting and rating photos.  There is always the possibility that
some problem, not necessarily within digikam - hardware, software elsewhere,
inadvertent user action - can corrupt the database and wipe out all of this
work.  For example, copying the database file (e.g. backup/restore, moving home
directories) without the appropriate options to handle a sparse file can make
it unusable, also bug 222774 describes tags being lost for some unknown reason.

There needs to be an option to dump at least the user-entered data into some
readable and archiveable format - plain text or XML - and restore it again. 
(Image metadata is not so important because it can always be re-read from the
images).  There needs to be an option to reference images by pathname/filename
rather than their hash, so that changes in album root or relative path can be
accomodated if necessary.
