If this should be a separate thread, let me know and I’ll create it, but in the keywordTags setting you show “Keywords”. My DAM (IdImager PhotoSupreme) writes each keyword to a tag named “Keyword (n)” where n is the number of the keyword. If there are 8 total keywords, You get Keyword (1) … Keyword (8) tags.
Does the Keyword entry in keywordTags pull information from numbered Keyword tags?
