I tried using hierarchical keywords in Bridge.¬ I had been redoing my file structure and got it to where I wanted it and I was experimented with bringing the photos into Lightroom.¬ The keywords were a real mess in LR.¬ I decided a non-hierarchical system was not so bad and that I didn't need so many - I wanted to undo what I had.¬ I imported the files into IV and created catalog sets to mirror my most important keywords.¬ I used File Info in Bridge to remove all the keywords and then used IV to sync the simplified keywords back into the files.
I worked well to a point but there were some persistent hierarchical keywords that kept popping up in Bridge and I couldn't delete them.¬ And even more would show up when importing into LR.¬ I think I have tracked this down to these sample lines in the XML sidecar files:
¬ ¬ <lr:hierarchicalSubject>
¬ ¬ <rdf:Bag>
¬ ¬ ¬ <rdf:li>People|People-Work</rdf:li>
¬ ¬ ¬ <rdf:li>Ratings|2Star|MP: 2Star</rdf:li>
¬ ¬ ¬ <rdf:li>Ratings|1Star|MP: 1Star</rdf:li>
¬ ¬ </rdf:Bag>
¬ ¬ </lr:hierarchicalSubject>
Is there a way to automate going through the sidecar files and removing every line between¬ <rdf:Bag>... <rdf:Bag> ?¬ The funny thing is I don't remember importing the originals of these files into LR, so I am not sure how these lines got in the file.
