I've deleted these tags directly at the database level. Cursory checks 
indicate everything is still well. I'm not completely sure of this, as 
apparently the Digikam database doesn't use referential integrity 
constraints (such as references and on delete cascade) at all :-O So 
some cruft may have been left in the database and some ill effects may 
still occur.

Digikam + Nepomuk: hundreds of synthetic tags

2011-04-28 Thread Michael Schuerig 

I'm using KDE 4.6.2 from experimental-snapshots and Digikam 2:1.9.0-1 
(re-compiled to work with 4.6.2). Looking around in the new settings 
offered by Digikam, I enabled Store metadata from Digikam in Nepomuk 
and Read metadata from Nepomuk (both in the settings for Metadata  
Nepomuk).

This had the intended effect of making image ratings and tags visible in 
Dolphin. At least I can search for ratings in Dolphin, I haven't found 
out about tags yet.

Unfortunately, there was another non-intended, negative effect. In 
Digikam, I now have literally hundreds of new tags like this

  nepomuk:/res/d3039469-bfc4-48ab-beaf-2717ae1ccb8a

As they make no sense at the user-level, I neither need nor want them. 
Presumably these tags have some internal purpose in Nepomuk, therefore I 
haven't yet started to delete them again manually. Besides, as I could 
only delete them individually, this would be a rather tedious chore.

Can anyone enlighten me as to the purpose of these tags? Is there any 
good reason that they are visible in Digikam? Is there a way to get rid 
of them, like munging Digikam's sqlite database?
