I would like to look at this from use cases both in the interest of packaging 
and third party applications using marblewidget. I list down some random 
points in no specific order and would like to see comments on them.

1) MarbleWidget should by default store user data in ".local/share/marble" on 
UNIX like platforms as defined by freedesktop.org instead of ".marble" as it 
does currently. Optionally, an application using the widget should be able to 
change this base location if it does not want to share its data with other 
applications. The QDesktopServices class allows us to get the user data 
directory in a cross platform way.

2) Plugins : Not all plugins developed for marblewidget are relevant to all 
applications that use the widget. An application should be able to select 
among the default plugins (provided by libmarble and libmarble-data packages) 
and also provide its own which are not seen by other applications. Is this 
currently possible?

3) Allow the application to provide its own DGML files to marblewidget which as 
with plugins are not meant to show up with other applications such as marble 
itself. This is my personal need as I may be using certain proprietary client 
provided maps. Access may even need authentication but i have not yet looked 
deeply into it yet.

4) As was discussed on IRC and the wiki it is clear that some minimal data 
needs to go with libmarble while the rest goes with libmarble-data. If there 
is some consensus on this then i could attempt the split.

I have been doing some work on this which can be seen at
