Hi!

I'm not sure if this would be the right approach, but you could use
Akonadi jobs to create, delete and modify alarms as suggested, but
then you could also at the same time use an items' model to maintain
an updated list of the alarms. This way in case if there' other
processes modifying the alarms you will get automatically the updates,
and you don't need to write the logic to get the alarms yourself. You
could inherit from Akonadi::ItemModel and watch for updates (connect
to signals like dataChanged, columnsInserted, columnsRemoved).

Just my 2cts =)
