In theory, no.

Modern application (as digiKam) use XMP now to store information.
There are copied as it can do in IPTC, but due to limitations (char
encoding + strings size), this way is prohibited now.

To import metadata from IPTC, there is a wrapper in digiKam core.
Please test with current implementation from svn, or at least
1.0.0-beta5, where this code has been improved since 0.10.0

If something is wrong, all is possible to improve it. We just need
original image to test in local with the detaisl of informations
hosted in images.
