[digiKam-users] Tags management

[ceinmart]

Hi, 

I just installed version 7. 

Unfortunately, tag management still very slow for me. 

I really want to reorganize my tags and open to any tips on how to achieve this.

1) at first, I don't need to apply the tag changes to the files.

2) I'm reorganizing into a tree structure, merging someones, moving others.

3) after reorganizing all tags, then I would apply to the files. 

Is this possible?

This process is very, very slow.  (I still believe it is slow because of the graphic tree view component, not the logical update process)

I'm really considering work directly into the database, with selects/updates. 

I believe will be much faster for me, since I familiarized myself with this. 

Considering I follow all rules of the relationship of the tables, is possible to do this? 

Is there any documentation about the relationship/rules of the tables tags in a way where I can use it as model to write my DMLs?

I never do this. more precisely, I use a flat tag structure with names
and subnames (Toulouse, Toulouse-Capitole, Toulouse-Capitole-facade...)

mostly because tree view is not portable, for example, I don't think web
galleries do support it

I find the tree structure useful, if only to avoid having an extremely long list of tags to scroll through (much of my tag structure is for wildlife and use a heirarchical scientific classification (eg animals>insects>lepidoptera>nymphalidae>nymphalinae). Usually I manually tag the photo with all of these levels, combined with other tags for locality. It depends on your preference, of course, but if all these tags are applied they will all appear in an export, if not in tree order.

I agree with what Rod' says and my use is also the same - to help maintain scientific classification of biodiversity pictures.

PS - New on the darktable list but unable to post queries so wondering if this gets through

Hi jdd, 

As far I noticed, when we save the structure of tags into a tree on DK and save to the picture file, the tags remain as unique *keywords* and as complement other properties save the tree structure :

Using the exiftool to check, here, using the DK Tag manager, I was moved the "3a etapa" into "bicicleta" tag and select the tags "brasil" and "sao paulo" which was configured into a tree before.

At least the keywords, they still unique.

I only don't understand why "bicicleta/3a etapa" is different from "brasil / sao paulo" , the " / " vs "/" 

Tags List         : bike, piedade,  brasil ,  bicicleta/3a etapa, ravelli,  brasil / sao paulo , 2015

Last Keyword XMP  : bike, piedade,  brasil ,  bicicleta/3a etapa, ravelli,  brasil / sao paulo , 2015

Keywords          : bike, piedade,  brasil , 3a etapa, ravelli,  sao paulo , 2015

As far I know, the "keywords" is mainly used by systems to get the tags.

Clearly not just me that does this then!
