When I add tags to a photo via Shotwell and then look at all of the exif data with exiftool I see that the Shotwell tags are stored under two different exif tag names - 'Keywords' and 'Subject'. I'm wondering what the difference is between these two? Is it in the different ways that other photo manager programs interpret tags? Thanks,

Answered my own question. 'Subject' is an XMP tag and 'Keywords' is an IPTC tag. Curious that there is no actual EXIF tag.
