Play Back and Skip Counter Example

This examples shows, how co:Counter could be specified as a play back counter (pbo:PlayBackCounter) and as a skip counter (pbo:SkipCounter) for a specific music track (here of the type mo:Track), related by the property pbo:media_object. Each time, when this specific music track was played, a co:ScrobbleEvent instance was created and linked to its play back counter with the property co:event_counter. This happened also, when this specific music track was skipped. The only difference is that such an event is related to its skip counter pbo:SkipCounter. To describe a scrobble events more in detail (besides event:time and event:agent), one can add properties such as co:application (to describe the application, which is related to the scrobbling activity, e.g. ex:iTunes) or co:device (to describe the device, which is related to the scrobbling activity, e.g. ex:MyPC). more...
