Feed Service
From Akregator
Fetching/Syncing
- Fetch feeds as specified in their settings (only fetch if a client is registered)
- Fetch on user request
- Notify fetching state
- Advanced: Write back changes to online services like Bloglines or Newsgator
=> here I am not sure what should happen in the kded daemon and what in Akonadi.
Archive management
When fetching/syncing:
- add feed articles to archive, update changed articles
- notify clients of new/updated/deleted articles, changed unread count
- delete expired articles
=> Akonadi
How to implement it? As "Resource", "Agent"?
