Katari provides KatariActivityService, an implementation of shindig ActivityService, and the related Activity entities: KatariActivity and KataryMediaItem. These entities are all mapped with hibernate.
As you can see, Katari uses the convention of prefixing 'Katari' to the name of the shindig interfase that it implements.
