These are very good points. Originally we didn't think about centrally stored data files or
files that need to be updated, nor about files on read-only media.
But after this round of gathering requirements we do. So our new file format will support
separation of student training data (statistics and confidence levels) and the original word
and multimedia data. This should satisfy your requirements that you list above.
It will also support keeping them together inside the same file, like you would use on a
personal computer when you create your own word lists. This is a common but much

I think we have most requirements now. I will write a first overview suggestion and put on
the wiki. Since most people seem to be preferring JSON over XML I will propose that.
Regarding the ease of use of qrc files, I am fairly certain that we will be able to do a more
or less in-place replacement API using the library that Andreas Xavier is working on.
