Write to IPTC Core Data of Image Files?

ExifTool looks good, very doable to drive from LC scripts.

Years ago we were using some proprietary web slideshow framework and I recall there was some discrepancy about where that framework thought a "caption" should go/could be found... as there is no such designated field as such in the IPTC spec: for very good reason: "Caption" is too broad and could be a container for one or more metadata depending on the use case: are you exposing a description only? the description plus photographer? A "label/title" plus a description? the filename?  date? etc... all could be placed in a container called "caption" in any given presentation layer context.. yes, it turned out to be a little can of worms once you got in.

My target fields are, initially, the IPTC "Description" and "Keywords" as they appear in Bridge. Where those among the "wandering-where-is-it metadata" that you found-could-not-be-read  previously?

This isn't directly helpful, but related information; when we needed to do
this for a client some years ago, we originally planned to do IPTC and XMP,
using the command line ExifTool. However, we found interesting variations in
what could be ready by which applications. In the end (the bit that makes it
particularly unhelpful since you want to run it on Linux) we found that the
best solution, ungainly thought it was, was to have our Rev app (as it was
then) direct GraphicConvertor through AppleScript to set the IPTC fields. That
produced the most reliably readable results. As far as I know, the client is
still using this tool in their workflow.

Checking my email archives, I find that that this was in 2008... so things may
have changed since then! But I would strongly suggest that you test a variety
of methods for setting the data, seeing how it can be read back in a variety
of apps.
