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.
