I've noticed that the behaviour of saving the identity tags into a JPEG 
differs depending on how you add a keyword. This seems very confusing and 
illogical to me and there is no information to the user about those 
differences:

- when editing digiKam tags from 'Comments & tags' side bar from main 
interface: all tags incl. photograpger and (c) rules etc. are saved perfectly

- when adding a keyword to a photo with right-click/context menu in album view 
only "keywords", "program" and "programVersion" are saved to IPTC, but no 
photographer/copyright etc. data, analogous  applies if you click a rating in 
the contect menu

- when adding a keyword by draging it from the keywords-filter sidebar to a 
picture in the album nothing gets saved into IPTC

- if you just want the "default IPTC identity informations" to be added to a 
picture, you have to go to the 'Comments & tags' side bar, selecting a 
keyword (or rating star) and deselect it again (at least this is the only 
method I found)

My proposals:

- keywords/ratings:
harmonize the way they are added to IPTC, so that there is no difference 
regardless of the method how the user adds it, i.e. adding keywords to IPTC 
too, when draging them from keywords-filter sidebar 
(or then make the method with the 'Comments & tags' side bar to the *only* one 
and drop the "halve-saving" when adding with right-click; in this case give 
information about this behaviour to the user in the Metadata settings)

- Identity: 
add select boxes to the identity settings for
[ ] always save to new pictures (= default)
    (i.e. only to pictures that are saved with "save as" in digikam)
[ ] save only when adding tags from 'Comments & tags' side bar
    (i.e. that is as it is now)
[ ] always save if not existing 
    (i.e. add identity info to all pictures in all albums, except if there      
    already are existing identity tags in the picture)
[ ] always overwrite with digikam informations (=dangerous!!! use with care)
    (i.e. always add the info from digikam settings to all pictures in all 
    albums, eventually overwriting existing tags) 

plus eventually I'd suggest (regarding 2nd option above):
displaying identity info in the Comments & tags' side bar (deluxe alternative: 
make this editable, but only for the actual picture(s) without changing 
digikam identity settings)

Finally (I hope I'm not too annoying..):

I miss a method to add IPTC-Data to a range of selected pictures. With the  
'Comments & tags' side bar I can add it to one single picture only. 

One can easily add a keyword to many selected pictures by draging it from the 
"keywords-filter" side bar - I often use this - but as said above, then it is 
not saved to IPTC. I have not found a possibility to add ratings or comments 
to several pictures with one action only.
