I think you can use an ItemModifyJob for that, just like any application would 
modify an item in Akonadi.
As a resource you don't have to get the item from Akonadi first, you can 
address it using remoteId for item the item's parent collection.

Do you have a collection hierachy or only one top level collection containing 
the items?
