How to access Report Package metadata

Narrative reporting has process data from the development of the Report Package that is gold for a continuous improvement / LEAN shop like King County. I would love to be able to access this data to glean understanding about which doclets had quality problems (were rejected more than others) which were delivered on time versus late, how late, etc.

Is there any way to get access to this information other than exporting the Report Package audit logs, parsing them, and then storing that data somewhere for analysis?
