Description Jesús Jiménez 2005-11-28 23:42:46 UTC 
Version:           0.8.0 (using KDE KDE 3.4.2)
Installed from:    Debian testing/unstable Packages
OS:                Linux

I usually create tags for both people and places. In order to organize them, I group them in tree-like categories, something like "Paris" and "Marseille" being children tags of "France", "John" and "Mary" being children tags of "Friends" while "Mom" and "Dad" being children tags of "Family", and so on. The problem is that, right now, if I tag a picture as "Paris", I must also manually tag it as "France". 

This is a quite annoying behaviour, because I usually only set bottom-level tags and, when I try to show, let's say, all France pictures, no one is shown because I've only set the cities name. I think the logical behaviour for digikam when a tag is set, would be to automatically set all of his parent tags or, said in other words, when a tag with children tags is selected, all pictures of her children tags should be shown. 

I don't know why anyone would prefer the current behaviour of independently setting parent and children tags. After all, a tree categorization implies that there's a relation between a parent and their children, and managing them as if they were independent is quite counter-intuitive.

It does exactly what you want, only you can not see it explicitly, if you select the mother tag france, paris will be shown.

"It does exactly what you want, only you can not see it explicitly, if you

This sounds a bit strange, because you dont want that kind of behaviour when  
you select the mother tag and then all the childrens are selected.  There is 
for each mother tag a relation ship with each child,  however not with all 
childs, but all childs have always have a relation ship with the mother tag. 
So at this moment digikam is not exactly doing what the writer wants. And 
what in my opinion is more logical behaviour.

Ops, you're right, Tom, it already works this way. It seems that I hadn't correctly tagged some of my pictures (so obviously the tag-based search didn't work well), and seeing that only children tags where checked led me to a wrong conclusion.

Anyway, I think that parent tags should be automatically checked when user checks a tag (or at least let it work this way with an option). Current behaviour is a little bit counter-intuitive.

Thanks for your attention and sorry for the confusion.

Werner: we think this system will work for most users, I agree it is a difficult area, but we have tried to make it as intuitive as we could.
