[Digikam-devel] Akonadi

[Jens Müller]

Hi all,

As this seems to be a hot topic, here are some of my thoughts:

- For a general exporter we need a api how to add, update & list items and 
collections, we can define our own api or use a existing one like KIO or 
Akonadi. With that api a host application can list collections inside their 
own and do the editing. That api should devide view (widgets, etc) from data 
so that each host application could show collections in their own prefered way 
(lists, trees, comboboxes), there should only be some 'hooks' to dialogs 
asking for new album properties etc.

- As there are existing apis we should consider them first instead reinventing 
the wheel.

- For KIO I also implemented a slave as a tryout listening albums and items. 
Keywords etc can be stored in own defined attributes inside the uds entries. 
But I did not found it usable as the item-idents change on the gallery api 
side. A items is identified by filepath on your local machine and by a id on the 
gallery api (flickr, picasaweb, ...) To sync we need to store it back to the 
local item, which I found problematic with KIO.

- For Akonadi we get a huge dependency (which I do not like) on board, but we 
have mechanism for caching and perhaps for synchronising. Thats why I tried 
this one out next.

- I do not know what's the opinion of each on the Akonadi approach, but there 
seems to be differencies.

- I build these tryouts only to know what about talking and to see where are 
the advantages and where are the disadvantages and if they can be solved.
- So building a tryout do not mean that this should be the preferend solution 
at the end.

If you have also do some research please let me hear on the results. I would 
also be encouraged to hear each's viewpoint on this topic.

Best, Jens
