feature-request: optional view of children of tag

[Harald Finster]

Hello,

first of all, I would like to congratulate you for
the phantastic work on digikam!

The following idea should be easy to implement
and would be extremely useful.

Would it be possible to show all images, which
are tagged by a certain tag and in addition all
images tagged with the tag's child-tags?

Consider the following tag-tree as an example

animal

    mammal

      bear
      dog
      cat

    bird

      blackbird
      raven

    insect

Currently, clicking on 'mammal' will show only
images tagged as 'mammal' but not images tagged
as 'bear', 'dog', 'cat'.

It would be more than useful (especially for categorizing purposes),
if this behaviour could be controlled, e.g. by a property of the tag.


Just a suggestion.

Greetings Harald

That should work in 0.8. Are you running a beta of 0.8? If so, please file a
bug.

after having solved some trouble with libkipi, I finally managed to
run 0.8.0 - looks very good!

And, as software-users are never happy - even with the best software,
I would like to suggest one more feature (probably more complex to
implement):

It would be nice to be able to tag tags.

The following example might illustrate, why:

Assume, you have a complex industrial plans consisting
of severals buildings:

I use tags to assign the substructures to images

steel-mill-xy
       blast-furnace-section-xy
           blast-furnace-xy-no1 <- image-of-bf1-a image-of-bf1-b image-of-bf1-and-bf2 ...
           blast-furnace-xy-no2 <- image-of-bf2-a image-of-bf2-b image-of-bf1-and-bf2 ...
           water-tower-xy-no1                       ...
           engine-house-xy                          ...
       oxygen-factory-xy
           converter-xy-building
           gas-holder-xy-no1
       hot-rolling-mill-xy


now, I would also like to categorize my images.
However, instead of directly categorizing the images, it would
be nice to categorize the substructures by adding tags, i.e.

industry
      mining
      steel-industry <- steel-mill-xy
          blast-furnaces <- blast-furnace-no1 blast-furnace-no2
          oxygen-factories <- oxygen-factory
          rolling-mills
              hot-rolling-mills <- hot-rolling-mill
              cold-rolling-mills
      gas-holders  <- gas-holder-no1
      water-towers <- water-tower-no1


So looking for images tagged with category 'steel-industry' would show all
substructures of 'steel-mill-xy' (and all images of it).
Looking for category 'gas-holders' would show all images of gasholders
('gasholder-xy-no1' in this case).

Hope, my example is not too confusing.

I would be willing to work on this, if someone would show me a 'starting-point'.

Greetings Harald

This is possible, just expand the left 'tag' view, make child tags, assign
images and click on the mother tag to view the those pictures, including
pictures with child tags.

Hello,

thanks for your kind reply, Tom!

yes, that's clear (with versin > 0.8)

Maybe, my example was bad. I'll try an other one to make the point clear.

Assume, you have the following tag-structure with locations as
parents of child-tags

'location-tags-tree'
--------------------

Germany

    Aachen
       Aachen-Cathedral
       Aachen-Cityhall

    Cologne
       Cologne-Cathedral
       Cologne-Railway-Station

France

    Paris

       Tour-Eiffel
       Notre-Dame-Cathedral


now, I would like to use a second structure to categorize my objects:

'category-tags-tree'
--------------------

buildings

       churches

       railway-stations

       city-halls


Instead of tagging individual images, I would like to assign the tags defined
in the 'location-tags-tree' to the tags in the 'category-tags-tree'.

In this example:

buildings

       churches          <- Aachen-Cathedral, Cologne-Cathedral

       railway-stations  <- Cologne-Railway-Station

       city-halls        <- Aachen-Cityhall



So, clicking on the mother tag 'Aachen' will show all images
of 'Aachen-Cathedral and 'Aachen-Cityhall' (this does already
work).
In addition clicking on 'churches' would show all
images of Aachen-Cathedral and Cologne-Cathedral

The point is, that the organizasion of tags is not resticted to
a tree-structure.


Greetings Harald

Hi Harald,

You can assign multiple tags to each image, and then you can make above query
by using the advanced search. This search can be saved and accessed as a
normal tag-folder.
