I've been using Lightroom Facial Recognition to identify people in my photographs. When I export these photographs from Lightroom this information is added to the "IPTC Extenson: Person Shown" metadata attribute value. I expected to be able to choose this metadata element in Caption Setup within InDesign. There are lots of choices but not Person Shown. It seems like there should be a way to do this other than moving this data into another field. Perhaps this is a feature planned for a future release?
