TMSU is the only such system I found useful without being cumbersome. After years of trying to use Git Annex, it was refreshing that TMSU doesn't alter the files in any way, merely storing all the (meta)data out-of-band in a separate DB.
These days I use TMSU via my own Emacs-based UI almost every single day, so thank you for that!
