Yes, we know this problem. 

In fact by default, digiKam do not removes all previous tags already set in IPTC.

A thread is already started in bugzilla about to add a new option to be able to not preserves old iptc keywords

Marcel,

I have take a look in this file.

Assign a tag to an image, tag is recorded to IPTC and XMP :

IPTC : as keywords
XMP : as keywords and tags path list into digiKam namespace.

Now, remove tags from your digiKam session. Nothing chnage in metadata. This is normal, because you need to synchronize metadata with DB.

If you do it, the synchronization will only update XMP::digiKam::tags path list, not XMP::keywords and IPTC::keywords. there is a wrong logic somewhere.

i suspect metadatahub.cpp, or perhaps method from KExiv2 to write keywords in IPTC or XMP. Any way, keywords just need to be cleared before to be written.

Your viewpoint ?

SVN commit 982571 by cgilles:

This is a long standing bug about Tag synchronization to XMP and IPTC keywords.
To wrap around this problem, we remove all previous keywords before to apply new sets.
Marcel, i think MetadataHub is right : new and old tags lists are fine. Problem must be in libkexiv2.
Anyway this patch fix the problem for the moment.
