@SeanMcCormack Jeffrey Friedl's plugin is an alternative to Lightroom's tracklog feature, so the OP already did this.
@stonecherub What exactly do you want to do? Write metadata to files? Lightroom still has a menu for that. You say you did this years ago in the stand-alone version of Lightroom, but AFAIK nothing has changed in this respect. What you did years ago should still be possible.
