Well, I don't think this is a Portfolio or iView issue, since Photoshop can read the IPTC data nicely. It's just that they didn't provide a way to map the data on import. So, my guess is, unless they decide this is a critical omission (which it is), we may be stuck with it until the next version. Which, as I said in my other post, severely cripples its utility for me, anyway.
Unless I decide to take a deep breath and start over in captioning and keywording, which I'm not inclined to do at the moment... <sigh>
