<br>
My iPhoto export project (at <a href="https://github.com/jensb/iphoto2xmp" rel="noreferrer" target="_blank">https://github.com/jensb/iphoto2xmp</a>) is making progress nicely.<br>
Since iPhoto always saves modifications as "versions" (mostly only a single version) I would like to keep this grouping in Digikam.<br>
<br>
What tags do I need to write into an XMP sidecar file to preserve the grouping of images in Digikam?<br>
Does Digikam support e.g. XMP derivedFrom and if so, what is the right syntax?<br>
<br>
Alternatively, what SQL command(s) group(s) images when applied to the Digikam database?<br>
This would be a hack but it would be better than nothing.<br>
<br>
Thank you!<br>
<br>
Regards<br>
Jens<br>
