I had a similar idea, but the implementation was a little different.
There would be an generic tag container (string->stringlist) that
would be completely independent of the file format. Every file format
implementation would then have two functions to import and export the
internal tags into the generic container. For now these functions
would be non-virtual and you would have to dynamic_cast the pointers
to get the right functionality, but in TagLib 2 we would simply make
them virtual and everything would just work.
What do you think about this approach? Would you be interested to work
on this as part of TagLib, not a separate library?
