Description Axel Krebs 2013-04-11 18:55:24 UTC

digiKam does _not_ sort tag, when adding/entering these

For this reason, simple search and organisation procedures will fail- there seem not even to be implemented!! 

Reproducible: Always

Steps to Reproduce:
1. when entering tags, didgikam should sort these exceptionless alpha-numerical
2. this could happen while entering the tags, or
3. maybe, even better in backround
Actual Results:  
At the given situation, digiKam does not allow to sort for tags whatever kind (as much as I understand)

Expected Results:  
digiKam should seriously consider aiming a database-standard procedure concerning handling information internally. 

Otherwise, there is a strong risk, that users repeat adding tags and meashing up the tag's database

this is a major issue, as this endangers the stability and compactiness of each database. I suggest to reconsider these, as they are widely accepted basics for database construction rules.

Hi Axel,

where exactly do you see the tags not being sorted? Could you provide a screenshot and mark that area?

Best regards,

Michael

Michael:

this refers to randomly sorted tags.
They do not foollow _any_ sort order, appearantly.

See pic with tags: "Hinweisschild", "Fahrzeug", "Wasser", "H", F", "W"

Instead of "F", "H" "W".

Hope I could explain, what I mean?

I have just some basic knowledge concerning databases, but i know well,
that there are three(?) steps for the normalisation of database content.

Comment 3 Michael G. Hansen 2013-04-11 20:21:08 UTC

Hi Axel,

my question was more about where in the digikam user interface you encounter the unsorted tags. In the left pane, in the icon view, in a menu, or in the right pane?

Sorry, I missed the screenshot ;-)

As much as I know, all Europeans use the same alphabet, and the sequence
I showed in my attachment was "Hinweisschild", "Fahrzeug", "Wasser",
that means FIRST letter is "H", "F", "W" INSTEAD of "F", "H", "W" for
"Fahrzeug", "Hinweisschild" and "Wasser".

As I indicated, this is NOT a minor issue but rather a major issue in
the context of databases.

You may want to check my wikipedia-link and some of the citations therein.

Comment 8 Michael G. Hansen 2013-04-13 18:42:33 UTC

Summary: Assigned tags shown below images in the IconView are not sorted. They are also not sorted in the tooltips.

Comment 9 Marcel Wiesweg 2013-04-18 19:45:44 UTC

They are probably sorted by (internal) tag id ;-)
Sorting criteria:
a) tag name
b) tag path
c) hierarchy depth

a - b?
c - a - b?
b - c?
