</div>You would have to check with Microstock what they mean by "TITLE". Most<br>
probably "HeadLine" or "ObjectName"?<br>
<br>
You can also have a look at IPTC web site, or directly at one of the<br>
documents describing the tags:<br>
<a href="http://www.iptc.org/std/photometadata/specification/IPTC-PhotoMetadata%28200907%29_1.pdf" target="_blank">http://www.iptc.org/std/photometadata/specification/IPTC-PhotoMetadata(200907)_1.pdf</a><br>
(page 27 compares the tags with Photoshop XMP).<br>

><br>
</div>Not yet in digiKam. I use MaPiVi to edit IPTC location for multiple<br>
images at once (but do not touch other tags like keywords, caption, etc.<br>
not to interfere with the way digiKam synchronises metadata).<br>
<div class="im">> 3. Looking on microstock web sites I see that photos are also well<br>

</div>I do not know here, but can guess: First, you need to find out if these<br>
are "IPTC keywords" or "IPTC categories" tags. "IPTC categories" are<br>
depreciated from the standard, so I guess these are keywords.<br>
<br>
digiKam uses hierarchy in keywords (stored as Xmp.digiKam.TagsList and<br>
synchronised to Xmp.lr.hierarchicalSubject for Lightroom compatibility).<br>
<br>
However, IPTC standard does not define hierarchy for keywords and the<br>
keywords are sync'ed to IPTC without hierarchy by digiKam. We could<br>
consider it a bug, but some people may actually like it. (I do not<br>
mind.)<br>
<br>
You can test yourself in digiKam (edit caption, keywords, ratings, iptc<br>
data manually) and quickly see all the tags (at the end of the list):<br>
<br>
$ exiv2 -pa imagename.jpg | less<br>
<br>
Since I store various information (incl. personal notes, which I do not<br>
want to get published on the internet) in the metadata, before<br>
publishing I use a bash script to re-organise the metadata to fit my<br>
needs.<br>
<br>
You could do the same: copying the hierarchy from XMP to IPTC keywords<br>
and then deleting everything but IPTC. exiv2 or exiftool would be your<br>
friends there.<br>
<br>
I can imagine that in the future, digiKam could have an export plugin<br>
allowing the user to define what information (a single branch in<br>
keywords hierarchy, no ratings, etc.) should be exported and how (in<br>
which standard).<br>
<br>
