Currently just plugins have access to the datastorage implementation. If there is a module that needs the data storage it has to be set from within the plugin. It would be nice to have a way to access the data storage from within the module without the need of a plugin. I imagine something like the mitkDataStorageService but accessible from within modules.
It would be really practical for us too.
Some polydata (surface , fiber) are not in world position when we load them. Having the DataStorage in a IO module would permit us to fetch the geometry from the a image, in order to modify the data while it's loaded or saved.
