I confirm also that mirroring with XMP namespace is working great
work Gilles.<br>
<br>
About IPTC I fully agree and understand the concept that it is
limited, however the actual way that Digikam deals with is by adding
the database content to IPTC<u> without removing the previous
content on that namespace</u>, resulting that tags that were
introduced by Digikam in the past, that may now be considered as
deprecated remain there, cannot be deleted and have a change to
reappear on the database if the images are shared with computers
with previous versions of Digikam (ej. 3.5.0) or other applications
that may focus on IPTC. It makes sense to me that Digikam should be
able to delete content that was added by Digikam. Maybe it can and I
just do not know how to use it.<br>
<br>
It just happened to me when sharing a catalog of photos with our
remote research station with limited Internet access to upgrade
Digikam (and its dependencies), many deprecated tags reappeared on
the database creating a huge confusion on the operators.<br>
<br>
It would be great to find a way to really erase the previous IPTC
keywords in the process that updates its content (instead of the
actual additions), removing that way deprecated tags on IPTC
namespace and that way we can move on XMP without leaving behind
deprecated tags in other namespaces.<br>
<br>
Just an idea about the subject... <br>
kind regards<br>

<pre wrap="">digiKam XMP namespace is used primary to populate digiKam database and
duplicate database metadata to image, WITHOUt to lost anything.
In second way, digiKam update also tags at other place in XMP and
IPTC, but this can introduce some leak about database properties (IPTC
for ex as serious limitation about strings. Nested Tags are also badly
supported in standard XMP namespace.

<pre wrap="">I mean other applications. Digikam isn't the only program in the
world that uses tags on images. By creating its own little private
place to keep tags it means it's never going to cooperate with other
programs using tags.
I mean what about images which one transfers to a web page and/or web
gallery? They use tags too.
I understand it may be difficult but without the ability to manage
tags in such a way that other programs can see and use them then they
are fundamentallyy useless (for me anyway).
