Thanks, Andrew. After sending my email, I came across Exiftool and Exiv2. Both seemed to do the trick, but the problem I am running into has to do with the way Photoshop reads and writes IPTC data - which seems to be non-standard (what a surprise). If I write the IPTC metadata in Photoshop, it’s invisible to the readers in those programs. And, if I write the data with those programs, Photoshop does not see it.
Looking through the docs for Exiftool, I believe it might be because PS puts the data in its own category header area. Unfortunately, I need the data to be viewable in PS. So, I am now researching a bit more to see if there is a standalone/commandline tool that will read and write Photoshop’s metadata… Thanks!
