Hi Arnd,

Thanks for your answer. It's no problem to extract the data (I use this quite 
often: I need to use my own mySQL database for the management of my photos - 
because it seems nobody is interested in talking about a professional tagging 
plugin... ;-(  ).

But the problem is to *insert* data. I tried, but with no success.

I extracted all data from Tags and TagsTree from "old version", changed all 
the numbers (added highest value of id in "new" to each id/pid in "old", so 
that there are not two identical ids), then added the overworked data from 
old tables to the new tables.

It all looks fine, but digikam doesn't show the inserted tags. It just ignores 
them and I don't know why???

When I add a new tag in digikam it gets the next id-number correctly. This new 
tag appears, I can use it, even after closing and reopening digiKam. But 
those tags "in between" that I have inserted directly into the tables just 
don't appear.

Any hints?

regards

Daniel
