<p>Hi Gilles,</p>
<p>Both, in the metadata viewer, it is as if there was no metadata regarding keywords (only the face regions seem to be there), so the only references to keywords are in IPTC and EXIF. And in the tags hierarchy, the keywords appear as a play list, having lost its hierarchy (makes sense, since only XMP metadata stores hierarchy). Maybe the metadata was wrong all along, and only now digikam has read it correctly, but I suspect the way XMP metadata is interpreted changed between digikam 7.3 and 7.4.
</p>
<p>Also, I don't know if it's related or not, but pictures taken with iphones seem to be problematic since digikam 7.4, with metadata not being written correctly into the file. I suspect it's only those containing faces, but I can't say for sure. Even if you correct it manually in digikam, metadata is not saved correctly to XMP, and tags also appear as a flat list without hierarchy. I believe it correspond to this bug report: <a class="moz-txt-link-freetext" href="https://bugs.kde.org/show_bug.cgi?id=436286">https://bugs.kde.org/show_bug.cgi?id=436286</a>
</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;">I store all my metadata changes in the pictures themselves (which is synced with the metadata), and I use a sqlite database stored in the local hard drive. I am using digikam Build date: 30/11/21 10:27 (target: Debug) Rev.: <a href="https://invent.kde.org/graphics/digikam/commit/3d2d9c9df3d9b8940502e89b83d39ce74a335754"><span style=" text-decoration: underline; color:#9cd4ff;">3d2d9c9df3d9b8940502e89b83d39ce74a335754</span></a> that I installed via flatpak.

<div>Hi,</div>
<div><br>
</div>
<div>Where did you see these changes exactly ? In the XMP
metadata viewer or the tags hierarchy from the right side bar
?</div>
<div><br>
</div>
<div>The metadata engine is Exiv2 shared library, and yes, it
has been released to last 0.27.5. This can have an effect on
metadata viewer contents.</div>
<div><br>
</div>
<div>Else, the tags hierarchy come from the database ? Wish
dtatabse type and version did you use exactly ?</div>
<div><br>

<br>
I noticed that today when I launched digikam (just updated via
flatpak), <br>
a few pictures lost their hierarchy in the tags, and their
tags appeared <br>
as being the same level. It happened to pictures that were not
modified <br>
for 4 or 5 years. Has there been any change in the metadata
engine, <br>
possibly interpreting XML metadata differently than it used to
until now?<br>
