For SCORM installed content, OC supports a property specified in the response to LMSGetValue(“cmi.launch_data”).
The optional property is called start_over and it can have two values 0 and 1; is the default if the property is omitted.
start_over=0 means launch the learning object using the tracking data state that was saved in the most recent previous launch for the specified user. If the learning object was never launched before then it will be launched in the initialized state. This is the default behavior.
start_over=1 means launch the learning object in the initialized state, regardless of how many times the learning object was previously launched by the specified user. Any previous historical data is saved in the content publisher system.
This feature is only supported for learning object launches for standard courseware content. It will be ignored for non-trackable learning objects.
