I've cleared out all of the confused discussion that was here, most of it based on misunderstandings about what, exactly, the problem is.
To summarize:
- justinhow has jAlbum set to link to images that are added to a project, rather than copying them.
- He added comments in jAlbum, and jAlbum copied those comments to the xmp.dc:description[1] field in the original images. So far, so good.
- He later edited the original images.
- His photo editor, alas, wiped out the XMP descriptions in the original images, which are needed for applications other than jAlbum.
- The comments are still present in the jAlbum projects, stored in their usual comments.properties location.
So, the question is how to induce jAlbum to write the XMP descriptions back to the original image files. The EXIF and IPTC fields are not involved at all.
We then come to
RobM's excellent tool, which appears to solve the problem....
